岩溶是建筑、公路、铁路等基础设施建设的重大地质隐患,利用地球物理方法对岩溶进行探测是岩溶地质调查的重要手段。本文论述了综合应用地质雷达法、高密度电阻率法和地震映像法的物探方法对安徽池州某建筑工地进行岩溶地质调查的工程实例。结果表明,综合应用多种物探方法,能有效查明灰岩地区岩溶的分布范围、埋藏深度和发育情况。
Karst is a major geological hazard in the construction of infrastructure such as buildings, highways and railways. Using geophysical methods to detect karst is an important means of karst geological survey. In this paper, a case study of karst geological survey of a construction site in Chizhou, Anhui Province, using geophysical methods such as GPR, high-density resistivity and seismic mapping is discussed in this paper. The results show that the comprehensive application of a variety of geophysical methods can effectively identify the limestone karst area distribution, burial depth and development.
