摘要:
为了揭示温度作用对地热桩承载性能的影响,建立了地热桩有限元数值模型进行分析。通过改变桩侧约束、桩端约束和桩土接触属性来模拟地热桩工作环境对地热桩温度作用效应的影响,得到不同工作环境下地热桩桩身轴力,桩侧摩阻力分布曲线。研究发现:桩侧约束越强,地热桩温度作用效应越显著; 桩端约束会改变中性点的位置; 桩土接触属性对地热桩温度作用效应影响并不显著。
Abstract:
A finite element model of geothermal energy pile was established to analyze the effect of temperature on load-carrying property of geothermal energy pile. By changing pile restraints and pile-soil properties,the effect of working environment on the temperature respond of geothermal pile was simulated and then the axial force distribution curves and shaft resistance curves were obtained.It was found that the stronger of the pile side restraints,the more notable the temperature affects. The position of neutral point was influenced by pile end restraints, and the effect of pile-soil interface properties was not significant.
