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 complexity of geological conditions in karst areas, in addition to the conventional survey methods, it is necessary to adopt the transversal electromagnetic wave penetrating technology with high detection accuracy to find out the characteristics of karst Groove and fracture zone) distribution characteristics. In this paper, taking LiTang sub-transmission station in Guangxi as an example, this paper introduces the application of trans-hole electromagnetic fluoroscopy in detecting and evaluating the reservoir karst ground. Some new information is obtained for the later site Evaluation, to determine the bearing layer of the pile and reinforcement of the foundation to provide detailed, real and reliable geological data.
