[Abstract] based on the finite element analysis simulation and the site investigation data of
deformation and damage of a corridor under a power station reservoir, this paper analyze
and explain the reason of longitudinal crack on the porch upper part of a pump storage
power station .the FEM simulation shows that the main reason of porch longitudinal crack is
that the constrain between the concrete structure interface is relatively weak, especially the
correspond glide friction force is relatively very weak .In this case, the corresponding still
glide friction coefficience f only equals which is much more smaller than ordinary data
f=~ in usual reference book.
