岩溶地区工程地质勘察方法探讨

Discussion on engineering geological prospecting method in karst area

岩溶作用的主要危害是岩溶区形成地下溶洞、上覆土体中形成土洞造成岩溶塌陷对建筑物造成破坏。采用常规勘探方法与高密度电阻率法、地质雷达法等物探手段相互验证的技术方式,查明了岩溶的基本分布,取得了良好的工程效果,并提出一些在勘察过程中应注意的问题。

The main harm of karstification is the formation of underground karst caves in karst areas and the formation of soil caves in overlying soil,causing karst collapse to destroy buildings.This paper adopts the conventional exploration method and geological radar method of high density resistivity method,such as geophysical prospecting means mutual authentication technology,the basic distribution of karst has been identified.It has achieved good effect of engineering,and puts forward some should pay attention to the problems in the process of investigation.
