摘要
混凝土坝常用泄洪方式为坝身孔口泄洪,该方式对结构整体性造成影响,应力集中也给坝体安全运行带来一定压力。本文结合实际重力坝工程,建立泄洪底孔底板及侧壁的三维有限元模型,计算不同工况下的结构应力变形结果,分析其分布变化规律,成果可为同类工程稳定性分析提供一定指导意义。
The common way of flood discharge for concrete dam is dam orifice,and the stress concentration also brings some pressure to the safe operation of the dam.Combined with the actual gravity dam engineering,the three-dimensional finite element model of bottom hole bottom plate and side wall is established to calculate the structural stress and deformation results under different working conditions and analyze its distribution change law,the results can provide some guidance for the stability analysis of similar engineering.
