实际工程中桩基往往被建设在临坡段地基上，且要承担很多水平荷载。该文提出了能够考虑临坡距和坡高的被动楔形体模型，以求解斜坡效应影响下的桩周极限土抗力。将其代入用来表征桩土侧向相互作用的p-y曲线中，再结合有限差分法，可以对水平受荷桩的响应进行求解分析。用该文方法结果与试验数据的对比验证了该方法的可靠性，所得结论对临坡段桩基工程具有重要的参考价值。
Abstract：In practical engineering,piles are usually built on adjacent slope foundation and are requied to bear significant horizontal loads. In this paper,a passive wedge model considering the adjacent slope distance and slope height is proposed to calculate the ultimate soil resistance considering slope effects. By substituting the model into the p-y curve representing the lateral soil-pile interaction and integrating the finite difference method,the response of horizontally loaded piles is analyzed. The reliability of the proposed method is verified by comparing the calculated results with experimental data. The conclusions provide important reference value for pile foundation engineering adjacent slopes.
