A Design And Optimization Of Guanmenzuizi Reservoir Of Gravity Dam Based On ANSYS

Guanmenzuzi reservoir is located in Hegang City,which is a water conservancy project under construction.The construction of the project will serve as a large-scale controlled water storage project at the upper reaches of the Wu Tong River in Hegang City.Gravity dam is the core of this water conservancy hydraulic building,once the crash will bring immeasurable consequences.Based on the engineering background data of Guanmenzuizi Reservoir of gravity dam,this article has carried on the standard design to the gravity dam section of the Guanmenzuizi reservoir.The ANSYS software is used to carry out the static load finite element analysis and the horizontal seismic inertia force finite element.The anti-sliding stability analysis of the dam body and the analysis of the deep anti-sliding stability of the dam foundation are carried out.Based on the design and analysis of the Guanmenzuizi reservoir of gravity dam and the relevant literatures,the optimization model of gravity dam section size is established by genetic algorithm,and the programming is calculated by VC ++ 6.0.After analyzing the defects of the traditional genetic algorithm optimization model,the adaptive genetic algorithm is introduced into the optimization of the dimension of the gravity dam.The optimization model is established and the dimension optimization program of gravity dam based on adaptive genetic algorithm is developed.By optimizing the size the Guanmenzuizi reservoir of gravity dam,it is shown that the adaptive genetic algorithm is superior to the traditional genetic algorithm in the selection and calculation of the parameters.The optimization results show that the gravity dam of the Guanmenzuizi achieves the minimum cross-sectional area and saves the concrete pouring quantity on the basis of satisfying the stability,and achieves the purpose of reducing the project cost and shortening the construction period.The research results of the paper have been adopted by the Heilongjiang Provincial Institute of Water Resources Hydropower Survey and Design for practical construction.
