基于CATIA的重力坝可视化设计

Visual design of gravity dams based on CATIA

以重力坝的设计方案为研究对象,将CATIA平台引入水工建筑物设计领域,建立了重力坝各个部分三维参数化模型。通过自上而下的三维设计理念,对重力坝各个部分的三维模型进行装配,在多视角、全景观的可视化环境下,完成了诸如地质模型构建、坝址选择、坝体结构划分、坝体模型建立、附属建筑物建模、各部分模型装配等一系列设计过程,实现了重力坝的三维模型化设计。该设计方案对重力坝设计提出了新的思路和方向,有益于重力坝的整套设计过程向集成化、参数化和智能化延伸。

Based on the design proposals of a gravity dam,the CATIA platform was introduced into the design domain of hydraulic structures,and the establishment of 3D parametric models for each part of the gravity dam was realized.According to the top-down 3D design idea,the 3D models for each part of the gravity dam were assembled.Under the visual environment with multi-angles of view and panoramic perspective,a series of design processes were accomplished,such as establishment of geological model,selection of dam site,division of dam structure,establishment of dam model,establishment of model for appurtenant structures and assemble of various models,and 3D model design of the gravity dam was realized.The present design proposal provides a new way for the design of gravity dams,and it is beneficial to integrate,parameterize,and intelligentize the whole design process of gravity dams.
