Finite Element Structural Analysis of Lock Chamber Based on Uneven Covering Layer Foundation

Abstract:

In order to explore the influence law of the uneven covering layer foundation on lock chamber structure, used the large-scale finite element software called ANSYS, chosen the first hub lock chamber on Guxue Hydroelectric Power Station which was under construction as research object, constructed a lock chamber model which had thickness variations of covering layer along the dam axis direction, calculated the results of displacement and stress distribution on lock chamber, the analysis showed that; the uneven covering layer only has impact on the displacement along thickness variation and vertical direction of the lock chamber, the affecting factor of the stress distribution on lock chamber is the size of the corresponding covering layer gap under the floor; the lock chamber deformation amount meets the operational requirements, the reinforcement on the floor of number (3) lock chamber should be strengthened, to meet structural stability requirements, it only need to have the minimum reinforcement rate reinforcement for the other two lock chamber floor and all the gate piers.
