拱坝泄洪表孔工作弧门支撑结构形式设计研究

摘要

This paper focus on analyzing the influence of bearing structure for service radial gate at upper outlets on arch dam under the same construction condition,by doing the finite element analysis to the model of arch dam.The size and distribution range are calculated under the different structural forms.This paper analyzes the stress distribution in different structural forms and provides a reference for the design of the bearing structure for service radial gate at upper outlets.%本文对带孔口拱坝整体模型进行有限元分析,研究同一工况下,弧门支座结构不同对拱坝孔口应力的影响.计算得到了不同结构形式下孔口群应力的大小、分布范围等.比选两种形式的弧门支座结构形式,分析不同结构形式下应力分布,为表孔弧门支座结构形式设计提供参考.
