| 摘 要： | 修建于深厚覆盖层上的土石坝,其防渗体系的可靠性直接关系到大坝的运行安全.针对硗碛直心墙土石坝防渗墙存在施工缺陷的实际工程特点,分别采用降低材料弹性模量以及设置接触面单元的方法对防渗墙的施工缺陷进行了模拟,分析了防渗墙局部缺陷对防渗体系应力变形以及大坝稳定性的影响.计算结果表明,防渗墙的缺陷对坝体应力变形基本无影响,对防渗墙自身的应力变形影响较大,应进行必要的工程处理.

| Abstract: | The reliability of seepage prevention system is directly related to the operation safety of earth-rockfill dam built on the deep overburden layer.In the practical construction,defects in the cutoff wall of Yaoji vertical core wall earth-rockfill dam were detected.According to the characteristic,methods of reducing the materials' elastic moduli and setting interface elements to simulate the defects are utilized.Besides,the effects of construction defects on stress-deformation of seepage prevention and the st... |
