利用管波信息进行定量解释的方法
The quantitative interpretation method based on tube wave information
摘要
Abstract
Tube wave detecting method has a good application prospect in pile bottom cavity detection of rock-socketed pile side and pile core pulling tests (pile body completeness);nevertheless,at present the method is mainly based on the qualitative interpretation of tube wave time section.In view of this situation,the authors,based on the past experience,put forward the utilization of tube wave informarion (direct tube wave arrival time,center frequency,reflection coefficient) for quantitative interpretation,and application of the combined qualitative explanation and quantitative interpretation,so as to improve the interpretation precision of the tube wave detecting method.The model pile experiment shows that the quantitative interpretation method with tube wave information is scientific and feasible.It can obtain good effect of geological interpretation,improve the foundation pile integrity and overcome the peephole view of core detection.关键词
