高面板堆石坝面板应力分布特性及其规律
Study on the stress distribution characteristics of face-slab of high concrete-face rock-fill dam
摘要
Abstract
It’s a key issue on keeping the safety of the face-slab to accurately grasp its static and dynam⁃ic stress distribution characteristics. In this paper,the three-dimensional nonlinear static and dynamic finite element mode GEODYNA is adopted to research the stress distribution characteristics of the face-slab un⁃der different cases such as the empty and full reservoir cases,under and after the earthquake. The distribu⁃tion of the zones in high tensile stress state and compressive stress state are researched respectively, and the influence of the geometrical parameters on the stress distribution of the face-slab is also studied. The results show that the high slop-direction tensile stress mainly appears near the bank and 4/5~2/3H area in the middle section of the dam, and the high axial-direction compressive stress area concentrates on the slab between the vertical joints in the central valley. According to these conclusions, some engineering aseismic measures on improving the stress of face-slab are proposed.关键词
