该文结合平和县东川水库大坝混凝土防渗墙工程实例,采用二维非线性邓肯(E-B)模型,对不同弹性模量、不同厚度的防渗墙进行应力、变形分析,为水库除险加固设计提供依据。分析结果表明:弹性模量对防渗墙应力影响较大,对变形影响较小;墙厚对防渗墙应力、变形影响均较小。 Based on the engineering example of concrete seepage prevention wall of Dongchuan reservoir dam in Pinghe County, this paper uses two-dimensional nonlinear Duncan (EB) model to analyze the stress and deformation of cut-off walls with different elastic modulus and thickness, Reinforcement design to provide the basis. The analysis results show that the elastic modulus has a great influence on the cut-off wall stress and has little effect on the deformation. The wall thickness has little influence on the cut-off wall stress and deformation.
