低应变反射波法试桩局限性的两个实例

Two examples about the limitation of the poise echo method

该文通过两个截然不同的实例,说明低应变反射波法试桩的准确性与测试对象及成桩过程有密切关系。反射波法虽然测试简单,波形识别分析也不困难,但过于依赖和相信其测试结果而忽略当时的实际情况,有时可能会造成误判。这是测试者应注意的问题。

This article uses two distinct real-life examples to illustrate that the accuracy of the pulse echo method is closely dependent on the proces about forming a pile. Although the pulse echo method is straight forward and the wave analysis is not difficult, the testers may draw incorrect conclusions if they rely solely on the technical data of test without taking into account other circumstantial facts.
