摘要
深厚卵石覆盖层地基的钢栈桥施工,存在钢管桩难以插打至有效嵌固深度,致使稳定性不足等问题。针对以上问题,结合致江路大桥主桥附近的水文及地质情况,提出采用“板凳桩+锚桩”的钢栈桥钢管桩结构形式,采用了特殊的施工工艺技术及其施工流程,有效解决了施工及使用期间栈桥稳定性不足、施工工期长、施工成本高等问题,为类似地质及水文情况下的钢栈桥设计与施工提供相关参考。
In the construction of steel trestle bridges with deep pebble overburden foundations,steel pipe piles are difficult to penetrate to the effective embedded depth,resulting in insufficient stability and other problems.In view of the above problems,combined with the hydrological and geological conditions near the main bridge of Zhijiang Road Bridge,this paper proposes the use of"bench pile+anchor pile"steel trestle steel pipe pile structure,using special construction technology and construction process,which is effective It solves the problems of insufficient stability of the trestle during construction and use,long construction period,and high construction cost,and provides relevant references for the design and construction of steel trestle under similar geological and hydrological conditions.
