厂房尾水薄壁堰三维非线性有限元分析

The 3-D Non-linear Finite Element Analysis of the Powerhouse Tailrace Weir with a Thin Wall

通过对厂房尾水薄壁堰-基岩-河水(水压力)联合作用的三维有限元分析进一步了解薄壁堰结构的位移、应力分布,堆石体位移、应力应变分布情况,岩体应力状态及应力分布等,为门机浇筑设计方案及薄壁堰加固等处理提供科学的依据和数据。

The further understanding of deformation and stress distribution of the thin wall weir structure, displacement and stress - strain distribution of rock - fill, and state and distribution of rock masses＇ stresses by making 3 - D finite element analysis of such a combined action as powerhouse tailrace thin wall weir bedrock river water（water pressure） has provided scientific basis and data for design of concreting for both the gantry crane foundation and reinforcing of the thin wall weir.
