摘　　要：BIM技术的出现,标志着水利水电行业进入一个新的阶段,BIM技术的应用已经是水利行业发展的必然趋势。该文基于BIM技术,选用CATIA软件作为三维设计平台以及ANSYS软件作为结构分析平台,利用两者之间数据文件接口,在CATIA平台创建重力坝挡水坝段三维参数化模型后导入ANSYS平台进行抗滑稳定和应力分析,并根据模拟计算结果进行设计方案调整直至满足强度和稳定要求,实现开发出一套基于BIM技术的集CAD/CAE一体化的重力坝参数化设计方法。The emergence of BIM technology marks that the water conservancy and hydropower industry has entered a new stage,and the application of BIM technology has been the inevitable trend of the development of water conservancy industry.In this paper,based on BIM technology,CATIA software is selected as the three-dimensional design platform and ANSYS software as the structural analysis platform.By using the data file interface between them,the three-dimensional parametric model of gravity dam retaining section is created on CATIA platform and then imported into ANSYS,the anti-sliding stability and stress of the platform are analyzed,and the design scheme is adjusted according to the simulation results until the strength and stability requirements are met.A set of parameterized design method of gravity dam based on BIM technology and CAD/CAE integration is developed.
