ABSTRACT
Sluice is widely used in hydraulic engineering. It is a low-head hydraulic structure using the gate to retain and discharge water. The working conditions of the sluice are similar to the overflow gravity dam on the rock foundation, but the water head is low, the flow is large, and it is mostly built on the soft-soil foundation in the plain area, so it has its characteristics in stability and settlement. Therefore, the design and calculation of sluice structures have been intensively studied globally. In this paper, three-dimensional finite element analysis is carried out on the whole structure of a soft foundation sluice, and the displacement and location of each structure are obtained by analyzing and calculating each sluice structure. Then the influence of different working conditions on the bending moment of the bottom plate is studied by finite element analysis. The single spring coupling element method is used to simulate the pile foundation of the interaction of piles and soil, the pile axial force, and the bending moment value of reinforcement to provide important reference data.
