    摘要:

    针对无覆盖层地质下钻孔灌注桩施工常用的满铺平台法和人造基床法存在成本高、工效低等问题,依托巴基斯坦中电胡布煤码头工程,提出基于桩顶支撑步履式顶推平台的钻孔桩一体化施工技术,实现恶劣海况和无覆盖层条件下钻孔桩高效施工。采用ANSYS软件对顶推平台施工全过程进行受力分析,研究施工过程的关键控制参数和计算方法。结果表明,桩顶支撑步履式顶推平台在不同荷载和工况组合下结构强度和刚度均能满足施工要求,为钻孔桩一体化施工提供了可靠的可移动平台基础。

    Abstract:

    The fully covered platform method and the artificial foundation bed method are often used in the construction of bored piles without overburden,but there are some problems such as high cost and low efficiency. Aiming at these problems,we rely on Hubco coal wharf project in Pakistan,propose an integrated construction technology of bored pile based on the incremental launching platform supported on pile top,realize high efficient construction of bored piles in severe sea conditions and without overburden,apply ANSYS to analyze the whole construction process of the incremental launching platform,and study the key control parameters and calculation methods of the construction process. The results show that the structural strength and stiffness of incremental launching platform supported on pile top can meet the requirement under different load and working conditions. It provides a reliable mobile platform foundation for integrated construction technology of bored pile.
