谈低应变反射波法检测桩身完整性

Discussion on Low Strain Reflected Wave Method in Detection of Pile Integrity

在桩身质量检测中,通常是由实测桩顶加速度或速度响应时域曲线来判定基桩的桩身完整性,一般普遍采用的是低应变反射波法。论文通过对低应变反射波法的测试设备和现场测试要求的分析,并结合相关图例,阐明了此方法能够普遍推广的相对完善的理论基础和比较先进的诊断技术。

We in the pile quality detection,is usually measured by time domain response curve of pile top acceleration or velocity,to judge pile integrity of foundation pile,generally used is the low strain reflection wave method.In this paper,through the analysis of test equipment and field test of low strain reflected wave method and combining with the relevant requirements,legend,clarifies the theoretical basis of this method can relativelyimprove generalization and advanced diagnosis technology.
