西村港跨海大桥栈桥设计与施工技术

Design and Construction Technology of Trestle Bridge of Xicun Harbour Sea-Crossing Bridge

以北海西村港跨海大桥项目修建的临时栈桥实例,通过施工重难点分析,介绍了跨海栈桥结构优化设计及施工关键技术,包括栈桥选址,西栈桥、通航栈桥与东栈桥总体结构设计参数,三维模型与最不利受力时的安全稳定性,解决了受潮汐和水文地质、雷暴区、通航段多次拼拆与重建等海洋环境条件下栈桥工艺技术难题,为类似工程施工提供借鉴。

Taking the temporary trestle bridge constructed by the Xicun harbour sea-crossing bridge project in Beihai as an example,through the analysis of the construction difficulties,this paper introduces the structural optimization design and the key construction techniques of the trestle bridge,including the trestle bridge site selection,the overall structural design parameters,three-dimensional model and safety and stability of the western trestle,navigable trestle and eastern trestle,the technical problems of trestle bridge under the conditions of tide,hydrogeology,thunderstorm area,navigation section and so on were solved.
