应力波反射法推断嵌岩桩持力层异常

Stress Wave Reflection Method Used to Infer the Abnormalities of Bearing Stratum Supporting a Rock-Socked Pile

本文结合106国道从化段田庄中桥1—1＃桩检测的工程实例,介绍基桩检测反射波方法的又一用途——推断嵌岩桩持力层是否存在软弱层(包括溶洞)。

How to infer if a soft stratum lies below the bearing stratum supporting a rock-socked pile. This paper describes a function of pile test by stress wave reflection method, which is used to test Pile 1-1# of Tianzhuang bridge in Conghua through Nation Highway 106.
