摘要
用反射波法检测桩身质量是在桩顶加一激振能量,引起桩身的振动,记录桩身的振动信号并加以分析,从而达到确定桩身材料强度、检查桩身的完整性、评价桩身施工质量或确定桩的承载力等目的.以厦门市丽景大厦为例,探讨了反射波法检测桩身质量的原理及方法,实践结果表明用反射波法检测桩身质量简捷可行的.
The hammer vibration energy is put on the top of the pile, which brings about the vibration of the pile to test pile＇s quality by wave reflection method. The vibration signal is recorded and analyzed in order to ensure pile＇s material intensity, examine pile＇s integrality, appraise pile＇s construction quality or confirm pile＇s bearing capacity etc. The wave reflection method on testing pile＇s quality is discussed at first. The Lijing edifice in Xiamen is taken as an example. The practical result indicates that the wave reflection method of testing pile＇s quality is simple and feasible.
