摘　　要：陆河抽水蓄能电站位于广东省陆河县新田镇境内,为查明上下水库基覆界面、不同风化带(全风化、强风化、弱风化—新鲜岩体)厚度、地质构造(断裂构造及节理裂隙密集破碎带)等重要工程地质信息,在区内系统开展了分辨率高、快速高效的高密度电法测量。结果表明:W1线高密度电法剖面推断存在5处断裂构造和1处节理裂隙密集破碎带;上水库覆盖层厚度范围为0~3 m,强风化层下限深度范围为1~40 m;下水库覆盖层厚度范围为0~29 m,强风化层下限深度范围为2~33 m。本文研究结果验证了高密度电法在中浅深度目标地质体探测工程中的有效性,为后期进一步开展工程地质评价提供了有效依据。Luhe Pumped Storage Power Station is located in Xintian Town,Luhe County,Guangdong Province.In order to determine the important engineering geological information such as the overburden interface of the upper and lower reservoirs,the thickness of different weathering zones(fully weathered,strongly weathered,weakly weathered to fresh rock mass),and geological structure(fracture structure and joint fissure dense fracture zone),a high-resolution and efficient high-density electrical measurement was systematically carried out in the area.The results show that there are five fracturing structures and one joints fissure dense fracture zone inferred from the high-density electrical profile of W1 line.The thickness of the overburden layer of the upper reservoir is 0-3 m,and the lower limit depth of the strongly weathered layer is 1-40 m.The thickness of the overburden layer of the lower reservoir is 0-29 m,and the lower limit depth of the strongly weathered layer is 2-33 m.The results of this paper verify the effectiveness of high-density electrical method in the detection engineering of target geological bodies at medium to shallow depths,and provide an effective basis for further engineering geological evaluation at the later stage.
