基于ANSYS的四川岷江犍为航电枢纽工程泄水闸结构分析

Ansys-based Structural Analysis of the Sluice Gate of Qianwei avigation and Hydropower Project in Sichuan Minjiang River

根据四川岷江犍为航电枢纽工程的实际情况,采用ANSYS三维计算对电站泄水闸三个坝段的结构应力结构进行计算分析。结果认为,岷江犍为航电枢纽工程泄水闸中间典型坝段(3#~25#坝段)地震工况的位移相对一般工况较大;在一侧检修工况下,泄水闸坝轴向位移较大。从应力分布情况来看,泄水闸的设计是合适的。边坝段(1#坝段)在检修工况下,闸墩顶部有较大的位移,门槽部位、闸墩底部产生较大的应力集中,经配筋计算分析,结构布置比较合理。

TIn this paper,Ansys three-dimensional calculation is used to calculate and analyze the structural stress structure of the three dam sections of the power station's sluice gate of the Jianwei Navigation and Hydropower Project in Minjiang,Sichuan.The result shows that the displacement of the typical dam section(3#~25#dam section)in the middle of the discharge gate of the Jianwei Navigation and Hydropower Project on the Minjiang River is larger than that of the general working conditions.Under the condition of maintenance on one side,the axial displacement of the sluice dam is relatively large.From the point of view of stress distribution,the design of the sluice gate is appropriate.In the side dam section(1#dam section),under the maintenance conditions,the top of the gate pier has a relatively large displacement,and the gate slot and the bottom of the gate pier have a large stress concentration.After calculation and analysis of reinforcement,the structure layout is relatively reasonable.
