摘　　要： 假设地基土体为半无限弹性体,考虑桩身的具体形状,分析了斜桩桩顶受任意平面荷载作用下的受力变形,并建立了积分方程式.采用数值方法,利用Gauss积分技术,得到了桩顶位移解答.对相同竖向荷载作用桩身不同倾角时桩顶沉降的特性,以及直桩在不同倾角的荷载作用下桩顶沉降特性进行了分析.以桩顶沉降控制作为桩基承载力设计的标准,认为直桩可以承受小于10°倾角的倾斜荷载,承受竖直荷载的斜桩可以有小于10°的倾角. An elastic analysis of batter pile subjected to inclined load was presented. The problems formed some integral equations developed from Mindlin's analysis for a point load embedded in a semi-infinite ideal elastic half space. Using numerical method and Gauss integration technology, the solutions of pile displacement were obtained. Two typical cases, the different batter angle of pile subjected to the same vertical load and the vertical pile subjected to different inclined load, were analyzed. The bearing capacity of the piles is found to depend on the load inclination and pile batter angle. The allowable settlement of pile head is suggested and vertical pile can bear load with inclination of less than 10°, and batter pile bearing vertical load can be angle of less than 10°.
