［摘要］以南京市某单管塔钢管桩为例，根据《建筑桩基础技术规范》（JGJ 94—2008）计算横向荷载作用下桩顶侧移、转角、桩身最大弯矩、桩底土压力等，并且运用SAP2000软件计算比较两种结果的差异和相似性，同时放大钢管材料的弹性模量模拟刚性桩，配合理论计算，将刚性桩结果与弹性桩结果比较得到两者差异性，为同类工程的设计以及校核提供参考。

Abstract:Combined with the steel pipe pile foundation of communication monopole in Nanjing, the top lateral displacement,  bending angle, maximum bending moment of the pile and the basal soil pressure were calculated under lateral load according to Technical code for building pile foundations（JGJ 94—2008）.The difference and similarity of two kinds of results calculated by SAP2000 were compared. The Young′s modulus of the steel material was magnified to simulate rigid pile with the theoretical calculation and the results of elastic pile and rigid pile were compared to obtain the difference of two piles, which can provide references for design and check the similar engineering.

Keywords:monopole; top lateral displacement;  soil pressure; pile foundation; elastic pile; rigid pile
