摘要
高密度电法是根据水文工程及环境工程地质调查的实际需要而研制的一种电探系统,该系统包括数据的采集和资料处理2部分。由于高密度电法可以实现数据的快速采集和微机处理,从而改变了电阻率法勘探传统的工作模式,大大提高了工作效率,减轻了工作强度,目前已在各个行业勘测中被大量运用。隧道勘察过程中,针对土岩隧道需要查清土岩分界面,为隧道设计、施工提供有力依据。论文通过实例介绍高密度电法在隧道勘察中查明土岩界面的有效应用。
High density resistivity method is a kind of electrical prospecting system developed according to the actual needs of hydrological engineering and environmental engineering geological survey.The system includes two parts:data acquisition and data processing.Because the high density resistivity method can realize fast data acquisition and microprocessor processing,which changes the traditional working mode of resistivity exploration,greatly improves the work efficiency and reduces the work intensity,and has been widely used in various industries.In the process of tunnel survey,the interface between soil and rock should be clarified in order to provide a strong basis for tunnel design and construction,This paper introduces the effective applicationof high-density resistivity method in identifying soil-rock interface in tunnel survey through examples.
