摘要：基于新修订水工结构设计规范的水工混凝土结构CAD系统，以中文Windows为操作平台，采用先进高效的VB语言和面向对象的程序设计方法，具有良好的人机交互界面.本文详细介绍水工混凝土结构CAD系统的总体设计原则以及文件系统、结构分析、素混凝土、钢筋混凝土、预应力混凝土、规范查询等功能模块的设计思-Abstract: Based on the newly revised Code for Design of hydraulic structures of hydraulic concrete structure of CAD systems to the Chinese Windows as the operating platform, using advanced and highly efficient VB language and object-oriented programming methods, has a good interactive interface. In this paper, hydraulic concrete structures introduced CAD system design principles, as well as file systems, structural analysis, plain concrete, reinforced concrete, prestressed concrete, standardized query features such as module design thinking
