三维勘测设计技术在水利水电工程中的应用研究

Application of 3D Collaborative Design in Hydroprojects

水电工程项目不仅规模大、涉及专业多、技术复杂,而且专业间需要不断反复地协调、数据的修改与转化,这对勘测设计手段提出了更高的要求。而三维勘测设计实践表明,三维勘测设计技术可以极大地提高设计效率、设计精度和表现效果,具有很强的实用价值和应用前景。首先介绍水利水电工程三维设计的构架与分解方法,多专业勘测设计的技术路线、设计思路和设计校审协同工作流程,骨架关联驱动技术和专业知识模板库技术。然后以某水电站工程为实例,探讨了三维协同设计的软件平台选择、应用流程以及测绘、地质、水工设计、计算分析、工程制图、动画表现等各专业各环节实现的全过程。

Hydropower projects are generally large-scale involving multiple professions and complex technologies. Continuous repeated coordination,modification and data transformation are needed among different disciplines,po-sing higher requirements for the design.Three-dimensional survey and design technology has huge advantage.We introduced the framework and decomposition of three-dimensional design for hydropower project,and described the technical route,design ideas and collaborative workflow between designers and proofreaders,skeleton associated drive technology and knowledge template.With a hydropower project as an illustration,we discussed the whole process of 3D collaborative design,including software platform selection,design ideas,mapping,geological,and hydraulic design,calculation and analysis,engineering graphics as well as animation.Practice shows that the 3D survey and design technology could improve design efficiency,design accuracy and performance results with strong practical value and application prospect.
