摘要
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。
According to the requirements of design and construction of the Shiquan Power Station, three-Dimensional FE-analysis is performed for the integral powerhouse dam section, including the upstresm and downstream wall, powerhouse, buttresses of the generators, spiral casing,droft tube, floors and foundation of powerhouse. The maximum stresses in each part of the structure have been determined and the displacement distribution rules has been estimated, which represents the integral behavior of the structure. Meanwhile the results can be taken as the basic information of powerhouse structural design.
