摘　　要：本文简要介绍了视电阻率联合剖面与高密度电法在吉林市北大壶滑雪场二道沟水库坝址勘查中的应用效果,通过用两种方法对水库坝址的勘查,有效的评价了北大壶滑雪场二道沟水库坝址存在着断裂破碎带,以及坝址在不同岩土地层下的特点及地球物理特性,用典型实例说明了视电阻率联合剖面和高密度电法在勘查岩土上下层电阻率变化规律、探测地基土均匀性等。发现并揭示了吉林市北大壶滑雪场二道沟水库坝址岩层存在着断裂破碎带,为下一步坝址设计施工提供了地球物理依据。In this paper,the authors briefly introduce the application effect of apparent resistivity coupling and high density electrical method in the exploration of Erdaogou reservoir dam site of Beidaogou Ski Resort,Jilin City.Through the exploration of the dam site by two methods,the existence of fracture zone and the characteristics and geophysical characteristics of the dam site under different rock and soil strata are effectively evaluated.A typical example is used to illustrate the variation of resistivity in the upper and lower layers of rock and soil,and to detect the uniformity of foundation soil.It is found and revealed that there exists fracture zone in the rock layer of Erdaogou reservoir dam site of Beidahu Ski Resort,Jilin City,which provides geophysical basis for the next dam site design and construction.
