高速铁路大跨度桥梁温度作用下轨道静态平顺性能分析
Static Irregularity Analysis of High-speed Railway Long-span Bridge Track under Temperature Load
摘要
Abstract
With reference to Nan-Guang railway Xijiang bridge of 450 m main span and based on the data of the railway track elevation measured by the works department, this paper studies the Xijiang bridge track static irregularities. The results show that the bigger temperature deformation accounts nothing for the failure to meet track static dimension standard and the track elevation can be controlled once the bridge deck deformation characteristics are investigated during track adjustment phase and track adjustment precision is controlled.关键词
