| 摘 要： | 目前深厚砂砾石地基墙幕结合防渗体系普遍采用10m的经验搭接长度，针对搭接长度在设计中偏于保守的现状，结合新疆下坂地水利枢纽工程，采用了有限元数值模拟计算和归一化处理的方法，在防渗体系不同深度布置尺寸和搭接长度的情况下，建立有限元数值计算模型，对防渗墙的受力和位移进行研究分析，计算分析出新疆下坂地墙幕结合防渗体系优化搭接长度度值，并总结出墙幕优化搭接长随防渗墙修建深度的变化规律，为深厚砂砾石地基墙幕结合防渗体系的设计和施工提供一定的参考。

| Abstract: | 10-meter experience lap length is widely used in wall and curtain combination anti-seepage system in deep sand and gravel layer.Based on the current situation that lap length is conservative on design and Xiabandi Water Control Project in Xijiang,this paper uses numerical simulation and normalization processing and has found the numerical simulation physical model by calculating stress and displacement of anti-seepage wall in different depth layout sizes and lap length of anti-seepage system,after analyzing and inducing variation regulation of anti-seepage system optimization lap length so as to provide reference materials for design and construction. |
