摘要
应用ANSYS软件对永定桥碾压混凝土重力坝4#坝段进行拟静力计算,分析了泄洪中孔在正常蓄水位和校核洪水位工况下的应力分布情况,重点分析了在地震作用下的应力分布情况,得出泄洪中孔在地震作用下的应力分布规律基本上与正常蓄水位的应力分布规律一致,量值略大,为泄洪中孔的配筋及结构优化提供了依据.
ANSYS software is applied to carry out pseuto-static calculation of 4# dam section of roller compacted concrete gravity dam in Yongding bridge.The stress distribution of flood discharge middle outlet under the working conditions of normal water level and check flood level is analyzed,espesially that under earthquake action.The results show that the stress distribution under earthquake action is the same as that under normal water level,and the stress is slightly larger.This can provide the basis for reinforcement and structural optimization.
