摘要:
对轴、横向荷载下微倾单桩侧向变形和内力进行研究，求得地基反力系数为常数时的解析解．采用Fortran语言编制了计算程序，并通过与模型试验结果进行对比来验证解及程序的可靠性．算例分析表明，桩身最大位移和最大弯矩随桩身初始倾角的增加而近似线性增大，且其变化速率随轴向荷载的增加而增大；桩身最大位移和最大弯矩随轴向荷载的增加而增大，且其变化速率随桩身初始倾角和轴向荷载的增加而增大．桩顶自由时桩身最大弯矩距离地面的距离随桩身初始倾角的增加而增大，且其变化速率随桩身初始倾角的增加或力矩荷载的减小而减小；桩身最大弯矩距离地面的距离随轴向荷载的增加而近似线性减小．所得解答使桩身侧向响应计算更符合工程实际．
Abstract:
The lateral deformations and internal forces of the slightly inclined single pile under axial and lateral loads were investigated, and the analytical solutions were deduced when the coefficient of subgrade reaction is a constant. The relevant computer program was developed with Fortran language, and a comparison with the model test results was made to show their validity. The calculation results indicate that both the maximum displacement and bending moment increase approximately linearly with the increase of the initial inclination angle of pile shaft, and their changing rates increase with the increase of the axial load. The maximum displacement and bending moment increase with the increase of the axial load, and their changing rates increase with increases of the initial inclination angle and the axial load. When pile head is free, the distance between the position of the maximum bending moment and ground increases when the initial inclination angle of pile shaft increases, and its changing rate decreases when the initial inclination angle of pile shaft increases or the moment load decreases. The distance between the position of the maximum bending moment and ground approximately decreases linearly with the increase of the axial load. The presented solutions make the calculation of lateral pile responses more accordant to engineering practice
