地震映射法在基岩空洞探测中的应用
|
摘要
地下隐伏洞穴的工程性质关系到建筑物的安全和正常使用,现有的地下隐伏洞穴探测方法受到场地工程条件限制,探测精度不足,采用地震映射法进行了建筑桩基基底空洞的工程实例探测与分析,探明了建筑桩基基底空洞的大小、形状和分布规律,工程验证结果表明准确度较高,取得了较好的探测效果。
The explorations of underground concealed cave could impact building safety and proper use.The existing geophysical detecting method was limited the survey accuracy because of observation conditions and test methods This paper had used the seismic imaging method to detect and analyze the engineering examples of empty holes of underground pile,and proved up the empty basement size,shape and distribution of the building pile.The results had indicated that the engineering test results had high accuracy,and achieved good detecting results.
