施工期厂房尾水薄壁堰三维非线性有限元分析

摘要

通过对薄壁堰-基岩-堆石体-河水(水压力)-门机运行荷载联合作用的三维有限元分析,进一步了解某水电站施工期厂房尾水薄壁堰混凝土结构的位移、应力分布,堆石体位移、应力分布情况,以期为施工期门机浇筑设计方案及薄壁堰加固处理方案积累经验.%According to the three-dimensional finite analysis on the operation lcading combined effect of thin-plate weir, bedrock, rockfill, riv-er-water (water pressure) and portal crane, the author investigates the displacement, stress distribution, rockfill displacement, and the stress distribution situation of the concrete structure of plant tail water thin-plate weir in one hydropower station construction period further, so as to accumulate experience for design scheme of portal crane pouring in construction and reinforcement and treatment scheme of the thin-plate weir.
