摘要
以北京至霸州城际铁路工程中的某2×100 m T构跨线桥作为工程背景,运用Midas/FEA有限元软件,对该桥墩梁固结处的局部应力进行分析,得到该桥0号块除个别位置出现集中应力外,其他均满足要求。通过计算结果对该桥的设计和施工提出合理的优化及改进措施。
Based on the design scheme of 2×100m T-Shapedprestressed concrete bridge on Beijing Bazhou intercity railway project,the local stress distribution of thepier-beam rigid joint was analyzedby using Midas/FEA finiteelement software.The result indicates that thestructural stress is reasonable except some individual location.In the end,the meliorated measure isproposed for future design and construction.
