针对能源桩受温度作用影响时的承载特性难以量化
提出考虑径向温度效应的荷载传递法对能源桩热-力耦合作用下的受力特性进行研究
评估温度变化对能源桩的影响
研究桩身轴力、桩侧摩阻力的分布状态
并以昆山能源桩的现场测试为依托
验证了本文方法的可行性。计算结果表明
温度作用对能源桩桩身应力应变状态有显著影响
当桩体受极限荷载与温度作用时
侧阻力发挥的作用几乎不大
在降温作用下能源桩桩顶会产生残余变形
因此在能源桩设计时应以降温作用时的沉降值为标准进行折减
考虑能源桩的设计承载力。
It is difficult to quantify the bearing characteristics of energy piles under the influence of temperature.The load transfer method considering the radial effect is proposed to study the force characteristics under the thermal-force coupling of energy piles.Temperature effect along the radial direction can be considered in the method.We can use this method to evaluate the influence of temperature changes on energy piles
and to study the distribution of the axial force and the lateral friction resistance of piles.Based on the field test on Kunshan energy pile
the feasibility of the method is verified.The calculation results show that the temperature has a significant effect on the stress-strain state of the energy pile.When the pile is subjected to the ultimate load and temperature load
the lateral resistance plays a little role.Under the cooling effect
residual deformation will occur at the top of the energy pile.Therefore
the settlement value should be reduced in the design of the energy pile according to the standard in low temperature condition
and the design bearing capacity of the energy pile should be considered.
