摘要： 某城际铁路K92+670～K107+550段和K108+790～K111+320段因市政工程建设导致高铁桥梁墩台发生不同程度的偏移，该区段高铁线路轨道的几何尺寸发生变形，严重影响轨道线路的平顺性和安全性。为确保铁路运营安全，选取适当的处理措施进行桥墩纠偏刻不容缓。结合此城际铁路箱梁顶升平移的纠偏工程实例，介绍了顶升移梁在线路纠偏中的应用。通过顶升移梁的原理介绍、工艺工法以及移梁监测系统，阐述了一种轨道线路横向偏移的整治方法。

Abstract: The viaduct piers between Stations K92+670 and K107+550 as well as between Stations K108+790 and K111+320 of an intercityrailway were observed to be tilted by various degrees due to a municipal engineering construction project. The geometric dimensions of the high-speed railway track in both sections were deformed, which was seriously affected the smoothness and safety of the track alignments. In order to ensure the safety of railway operation, it is urgent to select appropriate measures to correct the piers. This paper presents a case history of correction tilted piers by using the jack-up and shifting box beam method. The principles, key installation aspects and construction monitoring of the box beam jackup and translation method are introduced in the paper.
