摘要
Abstract
As an important water conveyance structure,culvert pipes under the dam are widely used in in earth-rock dam engineering.When the tower column structure of the water inlet hoist shaft encounters the design water level or even the check water level,the working gate slot and the maintenance gate slot in the shaft will often be filled with water,at this time,the stress state of the structure is different from that under the normal water level.In this paper,the finite element method is used to simulate a project and analyze the influence of sluice slot filling on the working behavior of tower inlet.The results show that the structural displacement and stress distribution laws are basically consistent under various working conditions,and the values are small.Under the check flood level,the bulkhead gate slot and the service gate slot are full of water.At this time,the structural displacement and the main tensile stress are less than the normal water storage level.Therefore,the water filling of the sluice slot can enhance the stability and safety margin of the structure.关键词
