摘要
根据桩土共同作用的工作特性,引入非线性接触单元将冻土地基的热弹塑性蠕变非线性有限元计算模型与混凝土桩联系起来,建立冻土区桩土共同作用的热弹塑性蠕变非线性有限元计算模型,计算结果与实测比较表明,该计算模型能较好地体现桩冻土共同工作性能。
Based on the working characteristics of the pile-soil interaction, using 3D non-linear contact element connects the thermo-elastic-plastic creep non-linear finite element calculation of the frozen foundation with concrete pile, and the thermo-elastic-plastic creep non-linear finite element calculation model of the pile-soil interaction in frozen soil is put forward. Comparison of computing result and test in situation, it shows that the model is suit to simulate the working function of pile and frozen soil interaction.
