中文摘要：
分别地，有堆积顶上或仅仅在胀大的土壤下面的应用负担的单个堆积任何一个的负担转移的有弹性的微分方程基于堆积土壤相互作用和砍变丑方法的理论被建立。为在广泛的土壤的单个堆积的负担转移的分析答案的推导能在此在广泛的土壤胀大下面借助于重叠原则被获得。二个工程例子的比较被做证明建议方法的可靠。分析结果证明这个分析解决方案能完成高精确，很少参数要求了，显示它在设计申请的简洁和有实行可能。采用的方法能贡献沿着堆积柄源于广泛的土壤胀大决定最大的紧张并且为设计设计提供可靠的底。方法能被采用与活跃深度，表面的垂直运动和大量堆积顶的变化沿着堆积柄获得轴的力量，解决和皮肤磨擦的各种各样的分发的曲线。
英文摘要：
The elastic differential equations of load-transfer of single pile either with applied loads on pile-top or only under the soil swelling were established, respectively, based on the theory of pile-soil interaction and the shear-deformation method. The derivation of analytic solution to load-transfer for single pile in expansive soil could hereby be obtained by means of superposition principle under expansive soils swelling. The comparison of two engineering examples was made to prove the credibility of the suggested method, The analyzed results show that this analytic solution can achieve high precision with few parameters required, indicating its＇ simplicity and practicability in engineering application. The employed method can contribute to determining the greatest tension along pile shaft resulting from expansive soils swelling and provide reliable bases for engineering design. The method can be employed to obtain various distributive curves of axial force, settlements and skin friction along the pile shaft with the changes of active depth, vertical movements of the surface and loads of pile-top.
