高密度电法在隐伏溶洞勘探中的应用
|
摘要
高密度电法即直流高密度电阻率法,它具有测点密度高,采集的信息量大和对探测的目标不造成影响等优点。因此,广泛的应用于隐伏岩溶溶洞的勘察中。本文以某在建小区的区域勘探为例,介绍了高密度电阻率法在探测地下隐伏溶洞中的应用。并用光滑约束最小二乘法进行反演处理,结合勘探成果进行综合解释,获得勘探区域内的溶洞的分布情况,为小区后期的安全施工提供参考。
High density resistivity method,namely DC high density resistivity method,has the advantages of high density of measurement point,large amount of information acquisition and the target of detection..Therefore,it is widely used in the investigation of karst caves.. This paper takes a case of regional exploration in a construction area, and introduces the application of high density resistivity method in detecting underground caverns.. And with smooth constrained least squares method inversion processing,combined with the exploration results of a comprehensive interpretation,to obtain the distribution of the exploration area of the cave,and provide a reference for the safety of the construction of the area in the late.
