Load-settlement calculation method for capped single pile
A load-settlement calculation method for a single capped pile comprises the steps that a stress model of the capped pile is analyzed, and pile cap mechanical equilibrium conditions of the capped pile are obtained according to a mechanical model; based on an improved shear settlement method, obtaining the total frictional resistance of the pile side of the capped pile generated by the combined action of the pile top concentrated load and the uniformly distributed load of the soil body below the pile cap; and further calculating through integral solution to obtain a formula of distribution of pile body settlement along the depth, which is related to the total frictional resistance on the pile side, and then obtaining a relationship between the load and settlement of the capped single pile. The invention provides a more efficient and accurate method in the aspect of load-settlement calculation of the capped single pile under the pile-soil interaction, the research content of the capped pile foundation is enriched, and time and economic cost are saved for guiding engineering practice, soft soil foundation reinforcement and the like.
一种戴帽单桩荷载‑沉降计算方法，包括戴帽桩受力模型分析，根据力学模型获得戴帽桩的桩帽力学平衡条件；基于改进剪切沉降方法获得由桩顶集中荷载和桩帽下方土体均布荷载共同作用产生的带帽桩桩侧总摩阻力；通过积分求解进一步计算得出与桩侧总摩阻力有关的桩身沉降沿深度分布的公式，随即获得带帽单桩荷载与沉降之间的关系。本发明在应对桩‑土相互作用下的戴帽单桩荷载‑沉降计算方面提出了更加高效和精确的方法，丰富了戴帽桩地基的研究内容，为指导工程实践和软土地基加固等方面节约时间和经济成本。
