摘　　要：文章针对云南大理弥渡县彭家庄水库在导流洞封堵后大坝下游渗漏量随着库水位升高而增大的现象,通过物探、钻孔勘察、压(注)水试验等勘探方法查明了水库渗漏的成因、范围及特点,结合彭家庄水库现有大坝防渗体系和施工条件,设计了在原防渗帷幕上游增设两排帷幕并加深帷幕底界,同时对隧洞进行加固补强的渗漏处理方案,解决了大坝渗流问题。In view of the phenomenon that the downstream leakage of the dam increases with the increase of the reservoir water level after the closure of the diversion tunnel of Pengjiazhuang Reservoir in Midu County,Dali,Yunnan Province,the causes,scope and characteristics of the reservoir leakage are found out through geophysical prospecting,drilling survey,water pressure(injection)test and other geophysical prospecting methods.Combined with the existing dam seepage control system and construction conditions of Pengjiazhuang Reservoir,a seepage treatment scheme is designed to add two rows of curtains in the upstream of the original seepage control curtain and deepen the bottom boundary of the curtain,and to reinforce the tunnel at the same time,which solves the dam seepage problem.
