摘要
随着高速铁路和公路交通的不断发展,涉及道路拓宽工程越来越多,研究道路施工过程对邻近高铁桥梁的变形影响,对维护高铁运营安全和满足轨道平顺性要求具有现实意义,为类似道路下穿高铁工程的施工和防护提供合理化建议和安全评估方法。
With the continuous development of high-speed railway and highway traffic,more and more road widening projects are involved.The study of the impact of road construction on the deformation of adjacent high-speed rail bridges is of practical significance for maintaining the safety of high-speed rail operations and meeting the requirements of track smoothness.Provide reasonable suggestions and safety assessment methods for the construction and protection of similar road underpass high-speed rail projects.
