【摘要】 防渗墙是最有效的平原水库地基防渗措施之一.为了更好地了解防渗墙的应力分布规律,根据常用的平原水库防渗墙的结构特点和受力特性,采用非线性有限元方法,研究了防渗墙墙体厚度、墙体的弹性模量、非均匀地基等对墙体应力大小的影响.得出在满足防渗要求的情况下,应优先选择弹性模量低的材料、墙体厚度宜控制在0.4m以内的结论,并认为当墙体底部存在软弱层时,应通过工程措施进行适当处理.更多还原

【Abstract】 The cut-off wall is one of the effective seepage control measures for the plain reservoir foundation.According to the structural and loading characteristics of the cut-off wall in the foundation of the plain reservoir,nonlinear finite element method is used to investigate the effects of the thickness,the elastic modulus of the wall and the heterogeneous foundation on the stress.更多还原
