高勒罕水库大坝高密度电法检测与分析

Detection and analysis based on high density resistivity method for Gaolehan reservoir

高密度电法检测方法不需要对大坝进行开挖破坏,成本低、时间短,能够揭示大坝内部信息。为此采用高密度电法对高勒罕水库土石坝下游坡的裂缝情况进行检测,同时结合监测资料和现场巡查等信息,分析判断大坝下游坡的开裂原因,并提出处治措施。

High density resistivity method can reveal inside information of a dam which takes a shorttime and low cost.At the same time,the method will not cause damage to the dam.For this reason,itwas to detect the cracks on downstream slope of Gaolehan dam.Combined with dam monitoring data andsite inspection information,the crack cause of downstream slope was analyzed and identified,and someremedial measures were given.
