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 assumption of the current “m” method, the internal forces and displacements of flexible piles under inclined load are analyzed. The aluminum piles are tested in the sand box under the inclined load of different model angles. It shows that the theory is in good agreement with the measured values. In addition, based on the polar plots of the ultimate bearing capacity at different inclination angles, an empirical formula for determining the ultimate bearing capacity under inclined loads is established, which has a certain practical value.
