那板水库渗漏原因分析OA

Regarding the leakage problem of Naban Reservoir,a preliminary analysis of the leakage causes was con-ducted from the aspects of dam seepage prevention effect,seepage flow behind the dam,dam foundation leakage,and leakage around the dam;then the possible leakage channels were explored and analyzed by geophysical pros-pecting;finally,groundwater connectivity tests were conducted by borehole tracer test method to verify the leakage channels speculated by geophysical exploration,and ultimately identify the causes for reservoir leakage.
