摘　　要：岔管是抽水蓄能电站地下工程设计的关键部位之一,本文基于结构优化设计理论,采用非线性有限元计算分析方法,考虑围岩和衬砌结构的联合受力特性,分别以衬砌厚度和配筋率为目标函数,分析岔管段围岩及钢筋混凝土衬砌的应力状态和变形形态,为确定岔管段合理的支护参数、衬砌厚度等问题提供理论依据,并提出建议配筋方案。Bifurcated pipe is one of the key parts of underground engineering design of pumped storage power station.Based on the theory of structural optimization design,this paper adopts non-linear finite element calculation and analysis method,and considers the combined stress characteristics of surrounding rock and lining structure.Taking the lining thickness and reinforcement ratio as the objective function,the stress state and deformation shape of the surrounding rock and reinforced concrete lining of the bifurcation section are analyzed.The purpose of this paper is to provide a theoretical basis for determining the reasonable support parameters and lining thickness of the bifurcated pipe section,and put forward a proposed reinforcement scheme.
