高密度电法是集电测深和电剖面装置于一体,具有观测精度高、数据采集量大、地质信息丰富、生产效率高等特点,在工程地质和水文地质勘查中被广泛应用。本文将高密度电法应用于贵州金沙某滑坡体调查中,通过分析该滑坡体的地质地球物理特征,验证了实施高密度电法调查滑坡体的可行性。调查中采用温纳装置,对该段滑坡体的地层结构、滑床位置及滑动面的埋深等地层情况的分析解释,证实了高密度电法应用效果良好,为进一步认识滑坡及其勘察治理提供了地球物理依据。
High-density electrical method is a combination of electric sounding and electric profile device. It has the characteristics of high observation precision, large data collection, rich geological information and high production efficiency. It is widely used in engineering geology and hydrogeology exploration. In this paper, high-density electric method is applied to the survey of a landslide in Jinsha, Guizhou Province. By analyzing the geophysical and physical characteristics of the landslide, the feasibility of applying high-density electric method to investigate the landslide is verified. The Wenna device was used in the survey to explain and analyze the stratum structure of the landslide body, the location of the sliding bed and the depth of the sliding surface, which confirmed that the high-density electric method has a good application effect. In order to further understand the landslide and its investigation and management Provided a geophysical basis.
