摘要
在理论公式的基础上,通过Abaqus软件模拟桩靴在土壤中的滑移过程,建立一种分析桩靴抗滑移阻力数值方法。首先研究各船级社抗滑移理论公式;在此基础上,建立桩靴-土系统有限元模型,利用CEL方法,建立研究所需工况,研究土体受力产生流动变形,得出抗滑移阻力数值解和土壤流动机制;最后将抗滑移阻力理论解与数值解进行对比分析与讨论。弥补现有理论公式不足,为计算桩靴抗滑移阻力提供一种精确的方法。
Based on the formula, the paper simulates the process of spudcan slide in the soil, and now to construct a numerical method to analye the anti-slide force of spudcan. First of all, the paper researches the theoretical anti-slide formula from different paper, based on which, the finite element model of spudcan-soil system is built to, using CEL method and establishing the required conditions, study on the flow deformation of soil and calculate the numerical result. Finally, the theoretical result and numerical result are compared and discussed to compensate for the lack of theoretical formula and provide a accurate method to calculate the anti-slide force of spudcan.
