摘　　要：由于岩溶地区地质情况的复杂性,在对重要建筑物的基础详勘时,除了采用常规的勘察手段外,还需采用探测精度较高的跨孔电磁波透视技术,以查清岩溶(溶洞、溶槽及裂隙带)的分布特征。本文以广西境内的黎塘分输泵站场的地基勘探为例,介绍了跨孔电磁波透视法在探测和评价储油罐岩溶病害地基中的应用,得到了一些新的信息,为后期的场地评价、确定桩端持力层以及地基加固处理等提供详细、真实、可靠的地质资料。Due to the geological complexity in the karst areas, it is necessary for the important buildings to adopt the cross--hole electromagnetic waves technique with high resolution in detecting cavities, karst troughs and fractures apart from selecting other routine ex- ploration techniques available. A prospecting example in Litang county, Guangxi Zhuang Autonomous Region was given in this paper to introduce application of cross hole electro- magnetic wave technique on detecting and evaluating karst geological disaster of oil--tank foundation. Some new geological data available would provide detailed, true and reliable geological information for building foundation appraisement, confirmation of pile- end supporting layer and groundwork reinforcement etc.
