摘要
强夯地基处理是一种常用的地基加固方法,其检测效果至关重要.瞬态面波法作为一种高效、非破坏性的地基检测方法,在强夯地基检测中具有广泛的应用前景.本文通过对两个实例进行总结分析,单纯的浅层平板载荷试验因其主要应力影响范围有限,不能有效全面反应整个场地的承载力情况.而通过采用瞬态面波法对场地强夯前、后进行检测,得到定性评价场地处理效果,再依据瞬态面波检测异常区域针对性进行载荷试验定量检测,得到瞬态面波与载荷试验之间的联系,从而大幅提高检测效率及检测结果可靠性.
Abstract
Dynamic compaction is a commonly used foundation improvement method,and its inspection effec-tiveness is crucial.As an efficient and non-destructive foundation testing technique,the transient surface wave method has broad application prospects in dynamic compaction inspection.This paper summarizes and analyzes two case studies.The shallow plate load test alone is insufficient in providing a comprehensive and accurate reflection of the bearing capacity of the entire site due to its limited influence range of primary stres-ses.However,by employing the transient surface wave method to inspect the site before and after dynamic compaction,a qualitative evaluation of the treatment effectiveness can be obtained.Furthermore,based on the anomaly areas detected by the transient surface wave method,quantitative load tests are conducted spe-cifically targeting these areas,enabling the establishment of a correlation between the transient surface wave method and load testing.As a result,the efficiency and reliability of the inspection process can be signifi-cantly improved.
