摘　　要：深厚覆盖层面板堆石坝变形的评价与控制是决定坝型进一步发展和推广使用的重要因素。文章以辽宁省关山水库大坝防渗墙为例,结合实测数据和模型计算成果,对面板堆石坝的地基防渗墙的力学和损伤特征进行研究。结论显示:关山水库防渗墙应力变形处于合理范围,不会产生开裂现象。文中研究思路和方法,可促进相关理论的完善和研究本身的深入开展。The evaluation and control of deep overburden layer faced rock-fill dam deformation are important factors determining further development, promotion and application of the dam type. The cutoff wall of Guanshan Reservoir Dam in Liaoning Province is adopted as an example in the paper. The mechanics and damage characteristics of the foundation cutoff wall of faced rock-fill dam are studied by combining the measured data and the calculated results of the model. The results show that the stress deformations of Guanshan Reservoir cutoff wall are within a reasonable range with no crack. The research ideas and methods in the paper can promote improvement of relevant theories and in-depth development of the research itself.
