摘　　要：哈尔滨市磨盘山水库防渗型式拟采用垂直砼防渗墙及帷幕灌浆方案,为了分析左岸不同长度防渗对水库渗漏量及坝基渗透稳定性的影响,对磨盘山水利枢纽区渗流场进行了三维数值模拟研究。结果表明,随着左岸防渗长度的增大,渗漏量及下游渗流出口渗透比降基本呈线性趋势减小。当左岸防渗长度为200m时,渗漏量及各渗透比降均小于允许值,为推荐的渗控方案。The vertical style seepage control scheme using concrete impermeable wall and grouting curtain was designed in Mopanshan reservoir of Harbin City. In order to analyze the seepage quantity and seepage stability of dam foundation under the situations of different impermeable body length at left bank, the authors studied the seepage field in Mopanshan hydroproject by threedimensional numerical simulation. The results showed the laws between the impermeable body length and the seepage control effect. The seepage quantity and the outfall seepage gradient in downstream of the dam is basically linear proportional to the impermeable body length at the left bank. When the impermeable body length is 200m,the seepage quantity and various seepage gradients are all less than the tolerant values, and this scheme was recommended.
