桩板结构上跨既有铁路桥墩基础的方案及安全分析

Scheme and Safety Analysis of Pile Slab Structure Crossing Existing Railway Bridge Pier Foundation

为确保既有铁路运营安全及施工人员作业安全,新建桩板结构桩基施工不能对既有铁路桥墩基础造成任何影响,所有施工都必须在确保营业线施工安全的前提下进行。通过对新建太原枢纽(北六堡)物流中心工程桩板结构跨大西客专线桥墩、太中银线桥墩施工,对桩板结构上跨既有铁路桥墩施工方案优化进行了分析。

In order to ensure both the railway operation safety and construction personnel safety,new pile plate structure of pile foundation construction can not cause any impact on existing railway bridge pier foundation,all construction should be carried out under the premise of ensuring safe construction.Through the construction of the pile plate structure crossing the foundation of bridge pier of Datong-Xi'an High-Speed Railway and Taiyuan-Zhongwei(Yinchuan) Railway in the New Taiyuan Hub(North 6 th Castle) Logistics Center Construction Project,this paper analyzes the optimization of pile plate structure crossing the existing railway pier construction scheme.
