摘要
鲁南高铁蓼河特大桥2×56mT构上跨京沪高铁路基,为准确分析新建鲁南高铁桥梁对既有京沪高铁路基的安全性影响,采用midas gts建立有限元模型进行安全评估,结果表明:新建T构桥对既有铁路路基的变形影响满足规范要求.
Abstract
The 2x56mT structure of the Lunan high-speed railway bridge is built on the Beijing-Shanghai high-speed railway foundation.In order to accurately analyze the safety impact of the new Lurun High-Speed Railway bridges on the existing Beijing-Shanghai High-Speed Railway foundation,a finite element model was established using Midas GTS for safety evaluation.The results show that the deformation effects of the new T-shaped bridge on the existing railway foundation and the impact on the track smoothness caused by foundation deformation both meet the regulatory requirements.
