Abstract
Because of its advantages of fast construction,good reinforcement effect,strong adaptability and high economic benefits,adhesive steel plate reinforcement technology has been widely used in structural transformation and reinforcement in water conservancy,electric power and other industries.Based on the finite element analysis,the paper discusses the reinforcement measures adopted by the steel plate after the partial excavation of the floor of a hydropower station.The results show that there is obvious stress concentration around the hole after the excavation,and the maximum stress at the junction of the hole increases by 57.89％.The reinforcement measures significantly improve the stability of the floor structure,and the maximum deformation of the floor can be reduced by 50％compared with the condition without reinforcement,which provides a safety guarantee for the floor reconstruction plan of the hydropower station,and also plays a certain reference for the subsequent construction of related projects.关键词
