黏土斜坡地基中水平受荷桩承载特性研究

运用ABAQUS有限元分析软件建立桩基-边坡耦合三维数值模型，并模拟黏土边坡中的不排水加载条件，分析了坡度分别为0°，15°，30°，45°，60°条件下，桩顶水平荷载分级施加时的桩身水平变形和弯矩分布规律及变化趋势，研究黏土斜坡地基中单桩的水平承载特性。结果表明:斜坡对桩基水平承载力的影响不容忽视，坡度越大，桩身变形及弯矩越大；单桩水平临界/极限承载力均随坡度的增加而减小，提出了黏土斜坡地基中不同坡度区间内的单桩临界/极限承载力折减系数。

Load-bearing Characteristics Research on Horizontal Load Pile in Clay Slope Base

A pile-slope coupled three-dimensional numerical model has been established by using ABAQUS finite element analysis software and the undrained loading condition of clay slope has been simulated. Pile horizontal deformation and bending moment distribution and the change trend have been analyzed when horizontal load on pile top grading on under respectively simulated slope angle of 0 °, 15 °, 30 °, 45 ° , 60 °, and the horizontal load-bearing characteristics of single pile in clay slope foundation is studied, The results show that the influence of slope on horizontal bearing capacity of the pile foundation cannot be ignored. The greater the slope is, the bigger the pile deformation and bending moment is. Horizontal critical/limit bearing capacity of single pile decreases with the increase of the slope. And the reduction coefficient of critical/limit bearing capacity of single pile in different slope intervals in clay slope base has been proposed as well.
