摘　　要：运用AutoCAD2007对拱坝廊道进行了三维可视化仿真模拟,通过对三维CAD的系统研究,表明基于特征的三维参数造型系统能够实现对复杂拱坝廊道的建模,系统通用性很强。作者直接从三维实体模型入手,根据实际数据绘制出三维廊道实体。在此基础上对三维实体进行了三维配筋,以及配筋信息标注和一定的可视化分析,实现了三维实体模型信息与钢筋配置信息相互关联。同时结合Autolisp编程,借助CAD平台还实现了对钢筋信息的批量录入与快速读取:在程序加载运行后,点取所关注钢筋,即可实时方便的获取钢筋信息。Based on AutoCAD2007, the virtual-reality technology for corridor in arch dams have been explored elementarily. Through a systemic analysis of 3D CAD shows that three-dimensional parametrization modelling system based on the characteristics can be con structed and its versatility is very strong. The authors have drawn 3D substantiality of corridor by actual data,and the design for 3D reinforcing bars have been made on the 3D model. Also the labling of reinforcement information and some visualization anylysis have been made. The information associativity between 3D substantiality model and 3D reinforcing bars have been realized. With Autolisp programing, recording and reading the steel bar information have been indicated simultaneously by CAD platform. After the program is loaded, the needed information can be read immediately.
