地下水封储油洞库水幕形成的质量是工程建设的关键,但是现阶段的检测方法均不能直观判断洞库整体水幕的形成质量,且都具有一定的盲目性。文中主要通过对储油洞库的水幕巷道两个测段进行水幕质量检测,对充水前后的视电阻率等值线图加以分析,来判断水幕的形成质量。分析结果表明:利用瞬变电磁对低电阻体(含水体)的高敏感性,对水幕形成(水幕孔充水)前后洞库水幕区岩体内的裂隙以及节理等构造的含水情况进行检测,并加以对比分析,可以直观地判断水幕的形成质量。
The quality of groundwater seal storage and accumulation reservoir curtain is the key to project construction. However, the detection methods at this stage can not directly judge the formation quality of the overall water curtain in the reservoir, and have certain blindness. In this paper, the quality of the water curtain is determined by measuring the water curtain quality of two sections of the water curtain tunnel of the storage cave reservoir and analyzing the apparent resistivity contour before and after water filling. The results show that the use of transient electromagnetic susceptibility to low resistivity body (water-bearing body), the water content of fractures and joints in rock mass before and after water curtain formation Testing, and to make comparative analysis, you can visually determine the quality of the formation of water curtain.
