摘要: 采用数值分析方法对深覆盖层上混凝土面板堆石坝的防渗墙应力变形性状进行了研究。研究了覆盖层特性、防渗墙混凝土特性、防渗墙施工顺序、防渗墙与坝趾之间距离和防渗墙形状对于面板堆石坝防渗墙应力变形性状的影响。总结出一些规律并提出相应的工程建议。Abstract: The stress-deformation behavior of diaphragm walls of concrete face rockfill dam built on thick alluvium deposit was analyzed using the numerical analysis method.The influences of the properties of alluvium deposit,the properties of diaphragm wall concrete,the construction sequence of diaphragm walls,the distance between diaphragm walls and dam toe and the shape of diaphragm walls on the stress-deformation behaviors of diaphragm walls of concrete face rockfill dams were studied.Some laws and corresponding engineering proposals were also put forward.
