摘　　要：随着计算机解决更为复杂设计问题的能力逐渐增强,桥梁设计必须突破现有的发展局限,向更为智能化和集成化的方向前进.笔者研究了基于方程组约束建立和求解桥梁特征和桥梁几何参数之间的映射关系,并通过特征依赖图建立桥梁构件间几何约束的映射,实现桥梁构件的参数驱动.同时,为了降低求解的复杂度,根据桥梁设计领域设计特征,对钢筋与构件和构件与钢筋之间的映射进一步简化.建立了桥梁智能设计的框架,为可重构的桥梁智能设计奠定理论基础.The capacity that computer can solve more complex design problem is gradually increased. Bridge designs need a breakthrough in the current development limitations, and go forward in the direction of more intelligent and integration. This paper develops the mapping relation between bridges feature and bridge geometric parameters based on constraint equations, and sets up geometric constraint mapping between bridge elements by feature dependence graph. Finally reconfigurable design processes was proposed to carry out parameter driving of bride elements, which establishes a theoretical foundation for reconfigurable intelligent bridge design.
