利用APDL语言编制了桥上无缝线路纵向附加力计算程序ALFCWR（Additional Longitudinal Forces of Continuous Welded Rail）
利用ANSYS有限元优化技术探讨了40+64+40m有碴轨道连续梁桥墩顶纵向水平线刚度的最小值
） Abstract： According to the rail-bridge-pier-foundation interaction analysis model of continuous welded rail on bridge, a program named ALFCWR (Additional Longitudinal Forces of Continuous Welded Rail) is compiled basing on re-development of ANSYS by using of its parameter design language
Based on engineering practice and taking the 40+64+40m continuous beam bridge as an example, this paper analyses the minimum longitudinal stiffness of it’s piers by using of the finite element optimization technology, the result can be served as reference when designing the continuous welded rail on continuous girder bridge
