摘要
针对北京局现有提速路段的概况,介绍了桥涵顶进在既有线改造中的应用情况,并结合工程实例,着重对顶进法施工中的方向控制、测量监控措施进行了论述,有效解决了桥涵顶进过程中方向跑偏的问题。
In light of the speed-improving railway section of Beijing railway bureau,the paper introduces the application conditions of culver jack-in in existing railway line transformation.Combining with the engineering example,it mainly discusses the construction direction control an measuring and monitoring measures of jack-in method.As a result,it effectively avoids culvert jack-in direction deviation.
