针对重庆市金佛山混凝土面板堆石坝初步设计方案，通过静力平面应力变形分析计算，分析了坝体在竣工期、蓄水期的应力变形分布规律，重点研究了主堆石孔隙率、次堆石材料对面板和趾板的应力变形、周边缝变位等的影响，为选取主堆石孔隙率、次堆石区筑坝材料提供依据。计算结果表明，主堆石孔隙率采用20.1%和19.1%均可行，次堆石筑坝材料采用弱风化带粉砂岩:页岩=7:3和弱风化带粉砂岩:页岩=5:5均是可行的。但是相对于其他方案，采用主堆石孔隙率为20.1%，次堆石筑坝材料为弱风化带粉砂岩:页岩=7:3的方案，坝体、面板、趾板的应力变形较小。

Based on the preliminary design scheme of Jinfo Mountain concrete face rockfill dam located in Chongqing, the stress deformation distributions of the dam during the completion period and storage period were analyzed through the stress deformation calculation on the static plane. The study was focused on the effects of main rockfill porosity ratio and secondary rockfill materials on the stress deformation distribution of the face slab and toe slab of the dam and the deformation of the peripheral joint, which can form the basis for the selection of dam materials. The calculation results showed that the main rockfill porosity ratios of 20.1% and 19.1% are feasible, and the secondary rockfill dam materials with the ratios between 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 rockfill porosity ratio of 20.1% and the secondary rockfill dam materials with the ratio between the weak weathered zone silty sandstone and shale of 7:3.
