Two-dimensional Finite Element Stress-Displacement Analysis for the Jinfo Mountain Concrete Face Rockfill Dam
摘要
Abstract
Based on the preliminary design scheme of Jinfo Mountain concret e face rockfill dam located in Chongqing, the st ress deformation distribut ions of the dam during the completion period and storage period were analyzed through the stress deforma-tion calculation on the static plane. The study was focused on the effects of main rockfill porosity ratio and secondary rockfill dam materials on the stress deformation distribution of the face slab and toe slab of the dam and the deformation of the periph-eral joint, which can form the basis for the selection of dam materials. The calculat ion results showed that the main rockfil po-rosity ratios of 20. 1% and 19. 1% are feasible, and the secondary rockf il dam materials with the rat ios bet ween the weak weathered zone silty sandstone and shale of 7: 3 and 5: 5 are feasible. The stress deformation of dam body, face slab, and toe slab is small with the main rockfil porosity rat io of 20. 1% and the secondary rockfill dam materials with the ratio between the weak weathered zone silty sandst one and shale of 7: 3.关键词
