摘　　要：针对铁路桥梁球型支座预偏量调节难的现状,文章首先应用TRIZ理论对现有预偏量调节方式存在缺陷的关键问题进行功能分析和因果分析,找到预偏量调节难的根本原因。其次利用物-场模型、技术矛盾等TRIZ工具进行问题求解,找到解决问题的求解方案,并通过方案评价模型找出最佳解决方案,成功设计出预偏量实时可调球型支座。最后通过理论及实物调节验证表明,该预偏量实时可调球型支座方案可行,且成功应用于部分高铁线路,有效解决传统预偏量调节的痛点问题,对支座预偏量调节实际工程具有重大意义。In response to the difficulty in adjusting the pre-deviation of spherical bearing in railway bridges,this article first applies TRIZ theory to conduct functional and causal analysis of the key issues in the existing pre-deviation adjustment methods,and finds the fundamental reason for the difficulty in pre-deviation adjustment.Secondly,TRIZ tools such as object-field models and technological contradictions are used to solve the issue,find the solution to the issue,and use the scheme evaluation model to find the most suitable solution,successfully designing a pre-deviated real-time adjustable spherical bearing.Finally,through theoretical and physical adjustment verification,it is shown that this pre-deviated real-time adjustable spherical bearing scheme is feasible,which has been successfully applied to some high-speed railway lines,effectively solving the sore points of traditional pre-deviation adjustment.It has significant implications for the practical engineering of bearing pre-deviation adjustment.
