复杂岸塔式竖井结构的动力响应分析OA
Dynamic Response Analysis of a Complex Shore-Tower Vertical Shaft Structure
云南省某水库复杂岸塔式竖井结构设有多个进水口,各进水口纵横交错,在高程上错落布置,竖井结构复杂,岸坡陡峭,受力条件复杂,整体稳定性问题突出.基于 ANSYS 有限元分析软件,通过 APDL 二次开发,构建竖井-基岩的三维数值模型,采用振型分解反应谱法分析复杂岸塔式竖井结构的三维动力响应特征,评价结构的抗震稳定性.结果表明:复杂岸塔式竖井在不同方向地震荷载作用下,最大位移值均发生在竖井顶部,最大拉压应力值均发生在最下部进出水口处,位移值和应力值满足水利工程抗震设计规范.研究成果可为该水库竖井结构设计提供重要参考.
A complex shore-tower vertical shaft structure of a reservoir in Yunnan Province is equipped with multiple intake openings arranged in a staggered manner both horizontally and vertically.The structure features a complicated configuration,steep bank slopes,and complex stress conditions,resulting in prominent concerns regarding its overall stability.Based on the finite element software ANSYS and secondary development using APDL,a three-dimensional numerical model of the vertical shaft-bedrock system was established.The modal superposition response spectrum method was adopted to analyze the three-dimensional dynamic response characteristics of the structure and to evaluate its seismic stability.The results show that under seismic loads in different directions,the maximum displacement occurs at the top of the shaft,while the maximum tensile and compressive stresses appear near the lowest intake-outlet opening.Both displacement and stress values satisfy the requirements of hydraulic engineering seismic design codes.The findings provide an important reference for the design of vertical shaft structures in this reservoir project.
