Abstract Research purposes: The demand for the special design of railway bridge piers is increasing. And the commercial software of railway bridge pier design does not exist by far. In order to help design personnel free from a mass of tedious drawing and calculation work, study on the parametric design platform system of the railway bridge pier which can do drawing and calculation work is carried out. In this paper, with the modular design, based on the VC7.0 platform with C++ language and Object ARX managed wrapper class, the design platform system of railway bridge pier based on AutoCAD secondary development is developed.

Research conclusions: (1)This software system has realized automatic output the design drawing of pier structural, pier cap, pier shaft, pier cap reinforcement and foundation. (2)This software system realized railway bridge pier's parametric design. So this software system can effectively improve design efficiency and reduce man-made error in the design and improve the work efficiency. (3)Taking the side pier design in the continuous girder bridge as the example, it is verified with regards to the reliability of the software. The results show that the parametric platform system is reliable.

Key words： railway bridge pier AutoCAD secondary development design and drawing
