摘　　要：该文主要探究基于BIM技术的水利水电工程智能系统的设计方法与应用效果。选择水利水电工程中的钢闸门作为研究对象,使用Catia建模软件按照确定装配层级、搭建骨架模型、建立零件结构和构建实体模型等步骤构建钢闸门的三维模型。使用Hypermesh软件将实体模型转换成网格模型并展开有限元分析,并选择强度和刚度2项指标判定钢闸门的工况是否符合设计标准。研究表明,钢闸门模型的横向位移呈现出中间大、两侧小和底部大、顶部小的分布特征,最大横向位移-9.489 mm,小于设计要求的-13.0 mm,故钢闸门的刚度合格;钢闸门的最大应力为135000 kPa,小于容许应力250000 kPa,故钢闸门的强度合格。另外,将该系统与其他学者研究的系统进行对比,该系统的响应时间快34.4%,应用效果更好。This papermainly explores the design method and application effect of an intelligent system for water conservancy and hydropower engineering based on BIM technology.The steel gate in the water conservancy and hydropower project is selected as the research object,and the three-dimensional model of the steel gate is constructed by using Catia modeling software according to the steps of determining the assembly level,building the skeleton model,establishing the part structure,constructing the solid model and so on.The solid model is transformed into a mesh model by Hypermesh software and the finite element analysis is carried out,and the strength and stiffness are selected to determine whether the working conditions of the steel gate meet the design standards.The results show that the lateral displacement of the steel gate model is large in the middle,small on both sides,large at the bottom and small at the top.The maximum lateral displacement is-9.489 mm,which is less than the design requirement of-13.0 mm.Therefore,the stiffness of the steel gate is qualified,and the maximum stress of the steel gate is 135000 kPa,less than the allowable stress of 250000 kPa,so the strength of the steel gate is qualified.In addition,compared with the system studied by other scholars,the response time of this system is 34.4%faster,resulting in better application effects.
