摘　　要：利用日本OYO公司MCOHM - 2 1型浅层地电仪 ,采用 pole pole方式高密度电阻率探测系统 ,对山东跋山、大冶、会宝岭等几个存在病险需要加固的大中型水库大坝进行了电阻率CT探测。坝体内的断层、破碎。Using the geoelectric instrument MCOHM 21 made by OYO Company, Japan, we did the high density electric resistivity exploration for detecting geology weakness of the water reservoir dam in Ba shan, Da ye, Hui baoling of Shan dong province with the pole pole array. The fault, fracture belts, geology weakness structure and some man made hidden drain caves are displayed very clearly on the resistivity profiles. Part of results has been proved by borehole data.
