| Abstract: | Through illustration of a hydropower project, three-dimensional finite element analyses of two structure schemes of exposed bifurcation and the embedded bifurcation with initial gap are carried out. The influences of surrounding rock performance and initial gap value on the stress of steel bifurcation and bearing capacity of surrounding rock are also discussed. Some significant conclusions are drawn through comparison of calculation results between the two schemes. |
