摘　　要：为了在可研阶段合理、快速地制定重力坝设计方案,减少设计周期和成本,采用极限状态设计的方法,利用VB 6.0可视化编程工具开发出了一套能够与CAD动态交互的重力坝三维设计系统。该系统通过对Auto-CAD的二次开发实现了重力坝的三维参数化建模,并对所建三维模型进行结构计算,将设计与计算紧密结合,通过动态交互简化了大量复杂数据的计算,达到精确、快速完成断面设计的目的。经实践检验证明,该系统大大提高了断面设计效率,实用性强,对可研阶段的方案比选具有重大意义。In order to make a design scheme reasonably and fast,as well as reduce the design cycle and cost in the feasibility study stage of gravity dam,this paper developed a 3D-CAD dynamic interaction design system with VB 6.0,based on the limit state design method.The system would produce 3D parametric models of gravity dam and fulfill the structural analysis.Data exchange would happen between the system and AutoCAD by dynamic interaction during the analytical process,which achieved the goal of accurate and fast dam design.In practice it has proved that the system greatly improves the efficiency of the section design and is practical strong.In brief,the system has a great significance to gravity dam design scheme selection in the feasibility study stage.
