Abstract
Based on the three-dimensional finite element method,the influence of concrete dam height on the structural stress characteristics and stress deformation of inlaid concrete face rockfill dam is studied by comparing and analyzing the design schemes of different concrete dam heights and conventional concrete face rockfill dam.The results show that with the increase of concrete dam height,the stress and deformation of rockfill dam body,face slab and concrete dam are reduced,especially the stress and deformation of face slab are obviously reduced,and the joint deformation is also reduced.In this study,the stress and deformation of the conventional panel dam and the concrete dam dam with the height of 40 m,60 m and 70 m are all within the allowable range,and each scheme is technically feasible.Based on the stress deformation characteristics and technical experience in panel dam engineering,it is recommended to choose a concrete dam height scheme of 60 meters.关键词
