| 摘 要： | 介绍了传统桩基检测中判别桩身混凝土质量的判据方法,在此基础上提出了一种新的参数分析方法——相对强弱指标法.这种方法综合了声速、波幅、频率、声时、PSD多方面的因素,通过比较,它比以往的判别方法更能够准确地对桩基质量进行定性分析,并且还能进行一定的定量分析.经过取芯验证,证实此法确实可行有效,有一定的实用价值.

| Abstract: | Based on introducing the criterion method for pile foundation quality inspection to assess the pile body concrete quality,this paper puts forward a new parameter analysis method,the relative strength index method.This method combines many factors such as sound velocity,amplitude,frequency,sonic time,PSD.By comparing with the traditional methods,it is more accurate on qualitative analysis on the pile foundation quality than the previous method.In addition,it can be applied to perform some quantitative analysis.Core verification testifies its feasibility and effectiveness. |
