Abstract: 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.

當代水电和水利工业的基础设施建设业务在不断扩大。传统的规划、演示、设计和构造方法显然无法满足当今大批量、短周期的水利设计需求。与传统技术相比,新技术能够解决当前的效率和质量问题,并促进建筑中的水电工程的发展,在各个方面都具有更大的优势。
通过BIM技术获得的模型具有很高的可视化程度,并且在纹理、性能、位置和复杂的运动关系方面使人们更易于理解和接受。其可以将设计者的意图和想法充分传达给用户,也更有利于更好的外观和合适的设计方案的出现,BIM模型可以由参数驱动,并且易于修改。设计人员可以修改设计方案中的某些约束参数以执行模型修改;通过这种方式设计的BIM模型也可以与结构分析软件CAE分析、信息传递和交换相结合,从而使原始设计计划的修改更加准确和可靠。因此,将BIM技术应用到水利工程设计中,与以往的二维设计相比,不仅提高了工程设计的质量、效率和水平,而且节省了人工和资源、材料,缩短了工期等。……
