倾斜荷载下基桩的受力研究

Study on the Behavior of Inclinedly Loading Piles

在现行“ｍ”法假设基础上，给出了倾斜荷载作用下柔性桩的内力及位移分析解，并以铝管在砂箱内进行了不同倾角的倾斜荷载作用下室内模型桩试验，实验结果表明，理论与实测值吻合良好．此外，还根据不同倾角下极限承载力的极坐标图，建立了倾斜荷载下确定极限承载力的经验公式，具有一定的实用价值．

Based on the current m method hypothesis,an analytical solution to deflection and internal force of flexible piles under inclined loads is presented in this paper,and model tests of flexible piles under inclined loads at various angles are carried out with aluminum hollow pipes in homogeneous sand.The calculation results show that the theoretical values agree well with the measured ones. In addition ,a practical empiric formula to determine the ultimate bearing capacity of piles under inclined loads is set up according to the polar bearing capacity diagram.
