摘　　要：深覆盖层上建土石坝已成为一种趋势,依据国内外具体的工程实例,总结归纳了深覆盖层上建土石坝存在的主要问题,并就渗漏和渗透稳定问题作了具体的分析.对于混凝土防渗墙防渗形式,应用了Fortran语言编制的饱和土二维渗流分析程序进行了渗流计算,计算结果表明其防渗效果良好.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.
