摘要
介绍了高速铁路三跨简支梁桥上无缝线路固定区温度伸缩力的试验研究成果,通过实测及理论计算,分析了温度伸缩力在墩台及钢轨上的分布情况。
The results of test study of temperature expansion force at fixing zones of the jointless track on deck of a 3 span high-speed railway simply-supported girder bridge are presented. Based on field measurements and theoretic calculation, the distribution of the temperature expansion force on piers, abutments and steel rails of the bridge is analyzed.
