摘　　要：针对传统常规挖孔桩施工慢、弃土处理难等问题,本文依托某220 kV输电线路的基础环境条件、受力特点及荷载情况,提出一种新型螺旋钢桩基础。采用有限元软件对该螺旋钢桩基础建模、开展承载力分析,并与理论计算方法进行对比。结果表明:模拟分析结果与理论计算结果吻合较好。本文结果可为类似基础工程设计提供一定的参考与借鉴。In view of the problems of slow construction of traditional conventional excavated piles and difficult disposal of spoil, a new type of spiral steel pile foundation is proposed based on the basic environmental conditions, stress characteristics and load conditions of a 220 kV transmission line.The finite element software is used to model the spiral steel pile foundation, analyze the bearing capacity, and compare with theoretical calculation methods.The results show that the simulation analysis results are in good agreement with the theoretical calculation results, which can provide some references for similar basic engineering designs.
