为了得到承台-倾斜桩体系在水平荷载条件下的工作性状，首先拟合现场实测数据得到土层及桩体的合理参数，然后采用数值模拟手段分析了不同倾斜程度及倾斜方向下体系的变形、受力特征。计算结果表明，3种倾斜方向及倾斜程度在0%~12%时体系水平向承载力均未减小，即水平位移均小于未倾斜时。从弯矩分布特征来看，桩顶均受到正弯矩，且弯矩值最大，桩身下部受到负弯矩，反弯点位于桩顶以下8~9 m处。桩体倾斜程度对体系中倾斜桩与竖直桩的弯矩分担产生影响。

To get the behavior of cap-inclined-pile under horizontal load, we implemented the following steps firstly, the reasonable parameters of soil and pile were acquired according to fitted field observed data, and then the characteristics of deformation and force under different inclined degrees and tilt directions were analyzed through numerical simulation. The results show that horizontal bearing capacity doesn’t decrease in the conditions of three tilt directions and inclined degrees from 0% to 12%. In other words, the horizontal displacement of an inclined pile is less than that of a vertical pile. Moreover, the top of the pile is subject to the maximum positive moment, whereas the bottom of the pile is subject to negative moment and the inflection point is 8-9 m below the top of the pile. Finally, the distribution of moment on tilted piles and vertical piles is influenced by the tilt degree.
