【摘要】：随着水工建筑物运用计算机软件进行设计全面普及,二维的CAD平面化设计已经不能满足人们的要求,三维参数化设计已经成为发展的必然趋势。而CATIA软件在世界上的CAD/CAE/CAM领域中属于领导地位,目前已广泛应用于航空航天、机械制造、土木工程等领域,并逐渐向水利水电、岩土工程、资源环境等领域发展。所以用CATIA软件对拱坝进行三维参数化设计是最优的选择。本文通过研究和开发CATIA软件,建立快捷精确的拱坝三维参数化设计体系。通过进一步丰富和细化拱坝设计模板,提出程序化的设计步骤,进一步提高建模效率和准确率,利用CATIA平台为水利水电工程创新设计创作条件。通过研究CATIA平台与Visual Basic程序的接口问题,运用Visual Basic语言方便快捷的编程能力,再充分结合CATIA自身强大的三维设计功能,扩展CATIA功能模块,可以更深层次利用CATIA三维参数化建立模型的能力。然后结合Visual Basic编程的计算拱坝抗滑稳定系数的人机互动界面,形成基于CATIA平台下拱坝坝肩抗滑稳定分析系统。运用刚体极限平衡法对拱坝坝肩的抗滑稳定问题进行分析,考虑拱坝坝肩抗滑稳定系数在二维、三维分析下,以及考虑各种地质情况下标准化的计算方法；在充分分析拱坝坝肩地质特性的基础上,采用Visual Basic语言进行人机交互式界面的开发,进行基于Visual Basic平台下的拱坝抗滑稳定分析功能模块的开发。本文是以三维设计软件CATIA为基础平台,研究并建立人机交换界面的拱坝三维设计体系,并通过二次开发工作,扩展拱坝基于刚体极限平衡法的二维、三维抗滑稳定系数分析功能模块,形成基于CATIA平台下拱坝设计-分析一体化的标准设计流程。
[Abstract]:With the wide use of computer software in the design of hydraulic structures, two-dimensional CAD plane design can not meet the requirements of people, three-dimensional parametric design has become an inevitable trend of development.At present, CATIA software has been widely used in aerospace, mechanical manufacturing, civil engineering and other fields, and has gradually developed into the fields of water conservancy and hydropower, geotechnical engineering, resources and environment, etc.So it is the best choice to use CATIA software to carry on the three-dimensional parameterized design to the arch dam.Through the research and development of CATIA software, a fast and accurate 3D parametric design system of arch dam is established in this paper.Through further enriching and refining the design template of arch dam, this paper puts forward the programmed design steps, further improves the efficiency and accuracy of modeling, and makes use of CATIA platform to create creative conditions for the innovative design of water conservancy and hydropower projects.By studying the interface between CATIA platform and Visual Basic program, using the convenient and quick programming ability of Visual Basic language, and fully combining the powerful 3D design function of CATIA, this paper extends the CATIA function module.It is possible to make use of the ability of CATIA 3D parameterization to build model in a deeper level.Combined with the human-computer interaction interface of Visual Basic programming to calculate the anti-slide stability coefficient of arch dam, the anti-slide stability analysis system of arch dam abutment based on CATIA platform is formed.The stability of arch dam abutment is analyzed by means of rigid body limit equilibrium method. The calculation method of stability coefficient of arch dam abutment is considered under two-dimensional and three-dimensional analysis, as well as various geological conditions.On the basis of fully analyzing the geological characteristics of arch dam abutment, the man-machine interactive interface of arch dam is developed with Visual Basic language, and the function module of anti-slide stability analysis of arch dam based on Visual Basic is developed.Based on the 3D design software CATIA, this paper studies and establishes the 3D design system of arch dam with man-machine exchange interface, and extends the two-dimensional arch dam based on rigid body limit equilibrium method through secondary development.A standard design flow of arch dam design-analysis integration based on CATIA platform is formed by the function module of three-dimensional stability coefficient analysis.
