During recent years，there are many bases of pile foundation quality affecting the normal working and safety of the building structures. Pile construction has high impercephbility and whose quality presents many incertitude factors，from an angel of qualitative inspection of the foundation piles, it has important significance for ensuring the quality and safety of foundation pile projects to modify the inspection methods and improving the inspection quality and the reliability of inspection & assessment results，it is also one of the research hotspots in foundation pile field. The main functions of low strain reflection wave method is to inspect the pile integrity, such as the judgment of pile defects positions, the checkout of pile lengths, and the qualitative estimation of the concrete strength grade，the judgment of the pile quality using the signal of reflected_wave curve accurately, the elimination of the project concealed harzard，and the estimation of foundation pile quality. This paper studied on the low strain reflection wave method for measuring of pile integrity made of Kelvin nonlinear elastic materials, set up a new one-way fluctuant model to treat the problems of piles made of Kelvin nonlinear elastic materials, gave out a dynamics equation of control volume，and induced the relation between pile axial forces and axial strain using the constitutive relation of one-way nonlinear elastic materials, put forward a new calculation method for the fluctuation of one-way nonlinear elastic materials, simulated the pile-top speed response time history curve (or displacement, acceleration) numerically using program written in FORTRAN language, finally the author set up a curve database of the foundation piles existing integrity problem for the integrity inspection of foundation piles in the future.

低应变是检测装身完整性的，高应变既可以检测完整性，又可以检测桩的承载力

一说到桩基低应变动力检测，相关建筑人士还是比较陌生的，桩基低应变动力检测基本概况怎么样？以下是中达咨询为建筑人士梳理相关桩基低应变动力检测基本内容，具体内容如下：中达咨询通过本网站建筑知识专栏的知识整理，梳理桩基低应变动力检测的相关内容：低应变桩基检测仪用于建筑、公路、铁路、桥梁、隧道等各个领域中，挖孔、冲（钻）孔、沉管等灌注桩及各种打入桩的完整性检测。随着我国经济实力的不断增强，建设行业正在以前所未有的速度飞速发展。在越来越多的房屋、水利以及公路桥涵的建设中，桩基作为一项典型的隐蔽工程在工程质量控制中起到了至关重要的作用。桩基的质量问题往往会影响整个工程的质量，严重的会对工程造成不可逆转的损害，甚至造成事故。桩基低应变动力检测主要目的：对于桩基的检验目的，主要是为了了解桩基的承载力，对桩基的混凝土质量进行检测，以验证其是否符合质量标准，还有就是对桩基本身的灌注情况进行检测，对桩基中存在的质量隐患进行排查，通过适当的手段进行补救，保证工程质量。桩基低应变动力检测主要原理：低应变反射波法检测桩基，主要是对桩基的完整性进行检测，对桩基的长度进行校对，检验桩基是否存在缺陷，并准确定位缺陷位置，以及对混凝土的强度等级进行估算。其原理是通过力锤或手锤敲击桩基顶部，使桩基产生应力波，应力波通过桩基，延桩基方向传播。根据一维弹性杆应力波波动理论，桩基中存在如断裂、夹泥、扩径、缩径、沉渣等情况时，应力波的波阻抗Z会发生明显变化，从而产生反射波和透射波，变化的程度取决于波阻抗Z的大小，也就是说取决于桩基中存在问题的严重性。通过安装在桩基顶部的传感器接收信号，对信号进行分析处理，分析反射波和透射波的相位以及幅值大小，可以有效确定桩基的问题位置和程度。桩基低应变动力检测影响要素：（1）低应变反射波法检测桩基的局限性（2）低应变反射波法检测桩基的影响因素更多关于标书代写制作，提升中标率，点击底部客服免费咨询。
