跨线桥深基础施工的路基防护技术

Roadbed Protective Technology of Flyover Deep Foundation under Construction

通过对各种施工技术条件的论证分析,采用钢轨桩支撑结合钢筋混凝土墙护壁的新方法,成功解决既有路基失稳、塌陷问题,保证既有铁路的运营安全,为跨线桥深基础施工提供切实可行的技术方法。

In this paper,adopt new method to combine rail-pile strut with reinforced concrete wall by proof analysis about various construction technology conditions,solve a problem of steadiness failure、subsidence for original roadbed successfully,assure the original rail transport security,supply flyover deep foundation construction with a feasible technology method.
