摘要

摘要: 假设地基为弹性体，考虑桩-土塑性滑移，建立微分方程，采用差分求解。经与实测资料对比，结果较为一致。该方法可以考虑桩周土体的连续性，可以分析竖向荷载作用下地基土体产生的沉降。将该方法与荷载传递法、剪切位移法进行比较，分析表明：该方法不是荷载传递法与弹性理论法的简单叠加；该方法在退化后可以分别取得与荷载传递法及剪切位移法比较好的一致性。

Abstract: The ground was assumed to be elastic. The differential equation was built and solved by finite difference method in consideration of plastic slip between pile and soil. The numerical example agrees well with the field measurement. Continuity of the soil around the pile can be considered into the method. By the method, the settlement of the ground around the pile can be calculated. The method was compared with load transfer method and shear displacement method. It is shown that the method isnt simple superposition of load transfer method and shear displacement method. Degradation of the method is consistent with load transfer method and shear displacement method respectively.
