摘要
假定桩土作用损伤变量的函数以及桩破坏时的状态,并选用理想弹性模型,导出了一组确定在损伤作用下桩顶轴向荷载—沉降曲线的解析算式,并由此分析了桩周和桩底土的影响以及桩承载力与其加载初始刚度间的关系。
Assuming the function of damage variables under the force of pile soil, and selecting ideal flexible model, it derives a.set of formulas of the load-subsidence behavior of pile under axial load considering damage, and analyses the influence of soil around pile and pile base and the relation between pile loading capacity and the initial stiffness of loading.
