| 摘 要： | 通过分析小直径钢管排桩的受力特点，提出了一种考虑桩土相互作用空间效应的平面刚架分析模型。将桩间岩土体以水平弹簧模拟，基于Winkler弹性地基梁理论，推导了钢管排桩的内力位移计算公式。以一滑坡治理现场堆载试验为例，对提出的计算方法与现场测试数据进行分析对比，二者吻合良好，本计算方法的可靠性得到了验证。同时在此基础上，也进行了相关主要影响因子的分析，得出桩顶位移与桩长呈现函数关系。

| Abstract: | Small-diameter steel tubular pile is widely used in slope engineering in recent years,but there is no perfect computation theory for reinforcing slope with it.Through the analysis of the stress characteristics of the small-diameter steel tubular anti-slide row piles,the new plane rigid frame model considering the pile-soil interaction is presented.Soil between row piles is regarded as a thin compressible layer and is simulated by a series of horizontal rings connecting the row piles.In this study,an analyti... |
