为解决某地区水资源缺乏的问题,应用电阻率联合剖面法、高密度电测深法、瞬变电磁法、大地电磁测深法和激发极化法等综合物探方法,对该地区地下岩溶、构造富水段进行勘探,目的是寻找红层裂隙水和碳酸盐类岩溶水。根据物探方法,圈定的富水地段,布置了多处水文地质勘探孔,经抽水试验,出水量在80～500M3/D,验证了综合物探方法在水资源勘查中的有效性。本文通过其中两个测区的实测资料,阐述了各方法的异常特征及其应用效果。
In order to solve the problem of lack of water resources in a certain area, comprehensive geophysical methods such as resistivity combined cross-section method, high-density electric sounding method, transient electromagnetic method, magnetotelluric sounding method and induced polarization method are applied to analyze the underground karst, Constructing a water-rich section for prospecting aims to find red-bed fissure water and carbonate-type karst water. According to the geophysical methods, a number of hydrogeological exploration holes are arranged in the delineated water-rich area. After pumping tests, the water output is between 80 and 500M3 / D, which verifies the effectiveness of the integrated geophysical prospecting method in water resources exploration. In this paper, the measured data of two test areas are used to illustrate the anomalous characteristics of each method and its application effects.
