本文结合石泉二期工程河床式电站设计要求,将厂房坝段的上、下游档水墙、厂房、机组支承结构、蜗壳、尾水管、底板及地基作为整体,用空间有限元法计算研究了在各种运行条件下的空间应力及变形分布规律.探明了该类结构的最大应力发生部位及结构的空间整体特性,为河床式电站厂房坝段的合理结构设计及配筋提供了可靠依据
Combined with the design requirements of Shiquan second-phase river bed-type power plant, the upper and lower archives water wall, plant, unit support structure, volute, draft tube, floor and foundation of the dam section are taken as a whole, and calculated by using the finite element method The spatial stress and deformation distribution under various operating conditions.The maximum stress place and the overall spatial structure of the structure are proved, which provides a reliable basis for the rational structural design and reinforcement of the powerhouse dam section of the riverbed type power station
