摘　　要：建筑场地内的岩溶、断裂构造等不良地质体引发的地质灾害严重影响建筑物地基基础安全,为了对不良地质体进行有效探测,发展了多种技术手段。本文论述了高密度电法和电阻率联合剖面法的勘探原理、施工方法,利用两种勘探方法相结合的方式,在广西某新建厂区建筑场地内进行岩溶勘查,并将两种勘测成果进行综合分析和类比,划定了场地内浅部岩溶及深部断裂构造位置。经实践证明,采用高密度电法和电阻率联合剖面法的联合勘查方式对岩溶和构造的探测是有效的。Geological hazards caused by karst,fault structures and other unfavorable geological bodies in construction sites seriously affect the safety of the foundations.A variety of techniques have been developed in order to effectively explore the geological bodies.This paper discusses the the principles and procedures of the high-density electrical method and resistivity composite profiling method.They were jointly applied to karst exploration in the construction site of a new factory in Guangxi,and their exploration results were compared and analyzed before the shallow karst and deep fault structures were located.It has been proved that the combined use of high-density electrical method and resistivity composite profiling method is effective for exploration of karst and structures.
