人工挖孔嵌岩桩低应变检测中的若干力学概念浅析

Some Mechanics Problem Analysis on Low Strain Integrity Testing of Mosaie Pile with Man-Excavated Shaft

本文从五个方面详细介绍了低应变检测技术中的一些常见问题:低应变检测的理论基础;桩底反射信号的识别;高频、低频波的选择;桩头处理方法;时域分析与频域分析的关系等,对工程实践中基桩检测技术的正确运用具有一定的参考价值。

In this article, five aspect＇s problem was sion, including theoretical base of Low strain integrity testing; Reflection signal identification on the bottom of pile; chosen between high frequency wave and low frequency wave; treatment on the top of pile; relation between time domain analysis and frequency domain analysis. It may be used as better reference material about installing correct Low strain integrity testing parameters.
