水库坝基处理措施

Treatment Measures for Dam Foundation of Reservoir

某水库已运行40多年，由于存在诸多险情，再加上大洪水的入库，坝后出现管涌，经综合比较采取塑性混凝土防渗墙方案，防渗处理之后该段坝后管涌得到明显改善，渗流得到有效控制。

A reservoir has been used for more than 40 years, and because it has many dangerous situations and the big flood may enters, the piping appears at the back of dam. After synthesis comparison, the plan of plastic concrete seepage prevention wall was adopted. The piping of downstream dam had distinct improvement and the filtration was under the active control after seepage prevention treatment.
