摘　　要：在墙幕结合的防渗体系中,上部防渗墙和下部帷幕灌浆的结构尺寸大多是凭经验取得的.文章主要从工程防渗效果及安全性、经济性等方面出发,应用渗流有限元数值模拟软件Seep/w,采用图解最大梯度法,对墙接幕防渗体系的结构尺寸进行优化,得出既能满足防渗要求,又能确保工程安全、经济的最优化深度.For the wall and curtain combination anti-seepage system,the structure sizes of upper cut-off wall and lower curtain grouting are mostly obtained by experience.From anti-seepage effect,safety and economy of engineerings,a seepage finite element numerical simulation software Seep/w is applied to optimize the structure sizes of the wall and curtain combination anti-seepage system so as to obtain the optimum depth not only satisfying the anti-seepage requirements,but also ensuring safety,economy of engineerings.
