| Abstract: | It has been becoming a trend to build earth-rock dams on deep overburden layer. This paper summarizes the main current problems about the construction of earth-rock dams on deep overburden layer through some specific engineering practices at home and abroad; and then it analyzes the stability problems caused by leakage and infiltration in detail. This paper also conducts the seepage calculation for the concrete cutoff wall by using 2-dimensional saturated soil seepage analysis program compiled by Fortran. The seepage calculation results show that the concrete cutoff wall has good anti-seepage effectiveness. |
