Study on the shape of super-high face rockfill dam with sloping compound structure

In order to solve the problems of large deformation and difficult maintenance of the super-high face rockfill dam, this paper innovatively proposes the slope-attached compound structure face rockfill dam. The difference between this dam and conventional rockfill dam is that a certain height of slope-attached concrete is set upstream of face rockfill dam. The finite element method is used to demonstrate the shape of the new structure, and the stress and deformation safety of the slope structure, face plate and rockfill dam are analyzed and evaluated. The research results show that it is feasible to set a certain height of sloping concrete in the upstream of the face rockfill dam, and it is also feasible to set a maintenance and drainage corridor in the slope, and this structure can effectively improve the safety and emergency maintenance conditions of the face rockfill dam.
