摘　　要：桩基础在施工过程中,由于基坑开挖或施工的原因会导致基桩发生倾斜倾。当斜桩的垂直度超过规范允许的偏差时,需对倾斜桩的竖向承载力进行计算验证。针对某建筑物桩基础发生倾斜,导致建筑物桩基竖向承载力减小的现象,通过对倾斜基桩水平位移、桩身弯矩、竖向承载力的计算分析,阐述了倾斜基桩承载力的研究方法;基于实际工程中相同荷载下不同倾斜率基桩,提出了倾斜率对基桩承载力的影响。During the construction process of the pile foundation,the foundation pile will be inclined due to the excavation or construction of the foundation pit. When the verticality of the inclined pile exceeds the deviation allowed by the specification,the vertical bearing capacity of the inclined pile needs to be verified. The article is aimed at the phenomenon that the pile foundation of a building is inclined,which leads to the decrease of the vertical bearing capacity of the pile foundation. Through the calculation and analysis of the horizontal displacement of the inclined pile,the bending moment of the pile and the vertical bearing capacity,the inclined pile is expounded. The research method of bearing capacity;based on the piles with different inclination rates under the same load in actual engineering,the influence of the inclination rate on the bearing capacity of the pile is proposed.
