预应力砼连续梁桥CAD系统几何模型的建立

Establisment of CAD System Geometric Models for Prestressed Concrete Continuous Girder Bridge

针对预应力混凝土连续梁桥，提出了一种几何模型的建立方法；建立了箱形梁构造的几何模型。在此基础上，成功地开发了预应力混凝土连续梁桥结构制图子系统。

A kind of establisment method of geometric models for prestressed concrete continuous girder bridge is given, and builds the box-girder constructional geometricmodels. In the conditions, the drawing system of prestressed concrete continuous girder bridge is completed by author.
