摘要
Abstract
In order to study the vibration of spillway pier under the action of high speed water flow,the stress distribution and vibration displacement of spillway pier under different opening degrees are calculated by three-dimensional finite element method.The calculation results show that the maximum stress of the pier is concentrated at the joint of the pier and the foundation,and the peak value of vibration displacement is located at the top of the pier.The stress and vibration displacement of the pier increase with the opening of the gate.Under the same opening degree,the stress and vibration displacement of single opening gate are greater than that of double opening gate.At the same time,in order to reduce the adverse effect of high-speed water flow on the pier,it is also proposed to add reinforced concrete beams to the top of the pier.Through calculation,the peak value of vibration displacement of the pier is significantly reduced after adopting the reinforcement measures.This study provides reference for other related engi neering design.关键词
