中文摘要：

为了模拟帷幕随机缺损对坝体及坝基渗流的影响,从随机概念出发,建立了模拟帷幕随机缺损的数学模型,重点考虑防渗体缺损大小、分布随机性对渗流场的影响,从而对防渗体施工的质量提出要求.通过一工程实例,说明了利用该随机缺损模型可以模拟帷幕的随机缺损,并对其进行渗流分析.

英文摘要：

In order to simulate the influences of random damage of grouting curtain on dams and seepage flows in dam foundation, a mathematical model was established based on the concept of randomness. The influences of the damage size and the randomness of damage distribution of the anti-seepage grouting curtain on the seepage field were highlighted, accordingly, requirements were put forward to the construction quality of the anti-seepage grouting curtain. An engineering case indicated that the random damage model could be employed to simulate the random damage of the grouting curtain, and the seepage analysis was performed.
