| Abstract: | 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. |
