Anti-seepage reinforcement design for the contact zone between dam body and foundation of Qingshitan Reservoir
It has been appraised that the dam of Qingshitan Reservoir has some problems,such as imperfection of an-ti-seepage system and filter drainage measures,seepage of dam foundation and around dam,abnormal seepage pres-sure distribution in the dam body,poor anti-seepage effect of the anti-seepage wall etc.Anti-seepage treatment is required for the dam body and foundation.For the dam body,plastic concrete continuous anti-seepage wall is select-ed after it is compared with the alternative of high pressure jet grouting continuous anti-seepage wall.For the dam foundation,curtain grouting is adopted and forms an anti-seepage whole with the core wall.An introduction is made on the comparison and design of dam reinforcement scheme for Qingshitan Reservoir.
