Research on the construction safety management of Civil EngineeringIn recent years, the construction accident in civil engineering in our country often occur. This not only caused casualties, also caused great loss of national property, and resulting in a very bad social influence. Therefore, in our country, the construction units in the civil engineering construction projects, shouldstrengthen the construction safety management, all aspects ofsecurity control for engineering, to prevent dangerous accidentsin the end it all. The cause of the civil engineering constructionaccidents are in many aspects. In order to enhance security,should be combined with the characteristics of construction projects and the enterprise's internal and external conditions, the rational allocation of production factors, optimization of management process. In order to realize the construction safetymanagement, construction units should establish a safety management system of a project, it should be carried out from the following aspects:A construction safety consciousness, cultivate the modern safety science theory, occurrence of unsafe human behavior causedcasualties. To implement safety management, it should becombined with psychology, behavioral science to strengthen the education and training of employees in production safety,improve the consciousness of safe production, so as to guide the safety production behavior of employees. For the construction enterprises should strengthen safety awareness and educationproject personnel, developing the regular safety education to the construction personnel involved in the project, and to carry outsecurity work. Three level education to the new participate in the work of the operating personnel; often transform types of employees, should be safety training for new types of work, makeoperation personnel matters needing attention can be familiar with the safe operation of the. In order to make safe productionconsciousness win support among the people, enterprisemanagement personnel but also in engineering project, using a variety of promotional tools to start a variety of education,cultivate the construction personnel safety consciousness. Andin the management of enterprises, the production safety systemthought to. Leaders at all levels and enterprises in issuing the project production task, should also carry out safety productionmeasures. Such as the production safety requirements to the construction personnel, so conducive to safe thought into the production of management, let each employee has consciously in the psychological sense of , the establishment of management system for safety in production in addition to strengthen production safety education and awareness of construction project staff, should alsoestablish a safety management system, protect the system from the construction enterprise safety in production of. In order toavoid the frequent occurrence of sudden accident, the construction enterprise should according to the project, to develop a comprehensive, the system of safety management,and invest the necessary manpower and funds to ensure the implementation of the project. Ensure the production safetyconstruction from the system implementation, the project section of construction enterprises should establish the safety inspectionsystem, and regularly to the project construction of the security check. Make a clear record of project construction process,record the dangerous post, and regularly check the work. Self evaluation and construction team every week to organize asafety activities, the project department to make regular safetyevaluation for project production. Construction enterprises in theconstruction of civil engineering, in order to establish a safety management system, need to make corresponding technical measures for safety management system, a comprehensivescientific standard for , the safety work of construction enterprise project technical measures should be prior to commencement of for engineering and technical measures should be strict examination and approval, the approval before implementation. If the design changes during construction, corresponding safety technical measures should be coordinated with the adjustment,will follow. The safety technical measures enacted personnel andparticipation, should fully understand the project as the construction scheme, construction environment, the actualoperation has, and combined with relevant laws and regulations or the security policy to establish safety technical measures,which can ensure the safety measures. In civil engineering construction of large, corresponding safety technical measuresshould be formulated more comprehensive and more specific,must be carried out through the whole process of construction,and mainly covers to other engineering safety. To establish the system of safety management, construction enterprises should also be strict safety before the construction of the project, technical personnel should to the technical measures for the construction personnelwork. Such as technical personnel issue written materials relatedto the construction personnel, and the implementation of safety technical measures of construction workers to regularly check;when technicians found construction personnel in violation oftechnical measure behavior, to give timely corrected. When theconstruction personnel technical mistakes when amended and supplemented immediately. In order to ensure the safety ofconstruction enterprises to implement, should take theseinspection of production safety measures the formation of rules and regulations, require employees to strictly abide by, so to ensure safety production system. At the same time, the construction enterprises can also follow the specific constructiondevelopment situation, formulate a set of safety technical measures linked to reward and punishment system, to strictly abide by the department or individual production safety, strictsecurity checks to reward, and if there are penalties for violations of the phenomenon. At the same time should have a goodproduction safety supervision work, and sent to the specialized production safety supervision work. When there is potential safety hazard factors in project development, should be timely analysis and inspection and make treatment immediately, so thatthe safety management to implement, implement the specificsystem, ensure the feasibility of production safety. The range ofcivil engineering projects involved in the construction processmore widely, because the factors which affect the engineering safety more. But in the construction process, the occurrence of safety accidents is often unexpected, with occasional andunexpected strong. These come unexpectedly accidents, serious damage often caused casualties and , strengthen the safety production and environment management in civil engineering construction process,environment is an important factor influencing the construction safety. So in order to guarantee safety in production, enterprises should be to strengthen the management of construction site. As in the construction site, the unnecessary equipment and surplus materials, should be timely treatment. In the pile construction materials in order to keep the construction site, the patency of the road accident, ensure to timely rescue, this is to protect the safety measures to realize. And construction enterprises shouldstrictly abide by the rules and regulations, which occurred on theconstruction site of the waste, garbage bag, cement, waste materials and other items should be clear, it can keep the siteclean, to create a civilized construction environment for safe construction. Create a safe production environment construction enterprises, should also be reflected in the risk disposal of equipment. For some such as the construction of electricity,dangerous equipment, cloth rod is used, should by the competent department of enterprise safety approval approval,the approval before they can be put into use after. And in the process of construction of civil engineering, a comprehensive analysis of the conditions of construction project. Some of the effects of environmental factors of the quality of construction, totake timely measures, and to conduct a comprehensivespecification, so that can realize the safe construction quality engineering to create good conditions.

Compressive behavior of concrete externally confined bycomposite jackets. 外部复合护套约束的混凝土压缩性Part A: experimental study Part A: 实验性研究This paper presents the results of an experimental investigation concerning the compressive behavior of concrete short columns externally confined by carbon and E-glass FRP jackets. The influences of different parameters such as the confinement level, the mechanical properties of the jackets and the compressive strength of the concrete core were studied. The results show that external confinement can significantly improve the ultimate strength and ductility of the specimens. The stress–strain response of confined concrete is bilinear: in the first linear zone, the behaviors of plain and confined concrete specimens are similar, whereas in the second pseudo-plastic branch, the behavior of confined concrete depends mainly on the jacket mechanicals properties. Test results demonstrate that the second part of (plastic) the stress–strain response depends on the jacket stiffness and that the ultimate strength of the jacket and the concrete strength are the most influential factors affecting the ultimate strength and strain of the confined concrete. Also, the study indicates that the confinement efficiency falls when the compressive strength of the concrete core increases.本篇论文阐述了有关于外部多重碳纤维和无碱玻璃纤维增强塑料紧箍护套的短柱混凝土压缩性试验研究结果。研究表明对其压缩性影响的因素有如约束层数，护套的力学特征，以及混凝土核心的抗压强度。研究结果发现试样的外部约束复合层对其极限强度和延伸性有显著提高。约束型混凝土的应力应变结果具有双线性特征：在一线区域，平面性能与约束型混领土压缩性试样相似，但是在第二伪塑性分叉区。约束型混凝土压缩性主要是靠复合层的力学性能支持。测试结果表明了第二部分（塑料）的反应主要是由护套的钢度支持，护套的极限强度以及混凝土的强度对约束型混凝土的极限强度和极限应变度影响因素最大。研究还发现约束效应在混凝土核心的抗压力上升后会降低。Keywords: Confined concrete; FRP jackets; HPC关键词：约束型混凝土 FRP护套 HPC
