摘要
基于常用的双折线荷载传递函数,本文导出了螺杆单桩的轴向荷载-沉降曲线的显式解,并且建立ansys有限元模型进行对比计算,再结合已有的螺杆桩静载试验P-S曲线进行对比,表明本文公式及有限元模型求解螺杆桩P-S曲线的可行性.并可以根据S-logP法判定螺杆桩的极限承载力,为螺杆单桩提供合理的承载力设计值.
Based on bilinear load transfer,this paper educes some solutions of Axial load-settlement curve of the single screw Stake and establishes ansys finite element model to calculate.When comparing the existing load test P-S curve of screw stake,the paper shows the feasibility of the formula for solving the screw stake P-S curve.and the rational design value of capacity of a single screw stake,thus the ultimate capacity of screw stake can be estimated by the method of S-logP.
