water intake towers;  finite elements;  stress;  Deformation

The inlet tower of a reservoir flood discharge project is a large-volume concrete structure, with complex body size, force and boundary conditions, and the lower part of the tower body has a large orifice flood discharge channel, and the bedrock is soft. According to the structural characteristics of the inlet tower, the finite element discretization of the inlet tower is carried out by using the space block unit, the strength and deformation of the inlet tower under seven working conditions are calculated, and the stress contour diagrams of several typical cross-sections are given, and some useful conclusions can be used as the design basis.
