摘要
Abstract
In order to restore the ecological connectivity of fish in the lower reaches of Dadu River,Tongjiezi Hydropower Project added a fishway 30 years after its completion.The new fishway is arranged by the right bank slope to excavate the upstream and downstream dam slope,and the reinforced concrete core wall is slotted for the construction of the fishway through the dam.The stress and deformation of the core wall before and af-ter slotting play an important role in the safe operation of Tongjiezi Hydropower Project.In this paper,the slotting of the core wall is taken as the research object,the structural stress analysis and displacement field a-nalysis are carried out by using three-dimensional finite element method,and the general law of structural stress distribution and deformation distribution characteristics are explored.The research results can guide the safety management and control of the core wall slotting construction period,and provide design reference for other similar projects.关键词
