摘　　要：本文用三维非线性有限元法,对长甸电站地下钢筋混凝土岔管在内水和外水压力作用下围岩、衬砌混凝土的应力和变形进行了分析,并通过对围岩侧压力系数、变形模量、摩擦系数及凝聚力等影响岔管和围岩应力分布诸因素的敏感性分析,得出一些有关钢筋混凝土岔管的结论。The stress-slrain of adjoining rock and concrete lining for underground reinforced reinforced concrete breeches pipe under internal and external water pressure in Changdian hydropower station is analysed by three dimensional non-liner finite element method. The conclusion of reinforced concrete breeches pipe is obtained through the analysis of sensitivity for adjoining lateral pressure coefficient, deformation modulus, coefficient of friction and cohesion influencing stress distribution of breeches pipe and adjoining rock.
