摘　　要：分析了某铁路桥桥墩开裂的原因,提出了对深度超过桥墩钢筋保护层厚度的裂缝,先采用深层压浆,再对表面开槽,并采用加固型混凝土进行置换的加固设计方案,并采用通用有限元软件ANSYS11.0对该桥20号墩的加固设计进行了有限元模拟分析。This paper analyzes the cause of cracking in piers of a railway bridge; it ment design scheme for the crack whose depth is more than the thickness of the layer of the bridge pier, that is, using deep grouting firstly, then slotting on the the grout by using reinforced concrete. This paper also carries out finite element ment design for Pier 20 of the bridge by means of using general-purpose finite el SYS 11. O. provides a reinforcereinforced protective surface and replacing analysis of reinforceement software ANSYS 11. 0.
