%X 螺杆桩是一种带螺牙的特殊桩型。由于其桩侧螺纹段的存在，与常规桩型相比，其桩侧受力不同。而螺纹段受力又与螺距相关，本文根据不同螺距，提出不同螺纹段土体的破坏模式，并得出了不同的螺距情况下的螺杆桩极限承载力计算方法，并结合实际案例与数值模拟发现本文提出的理论更加贴合实际。<br />
Screw pile is a special type of pile. Because of the existence of the screw section on the side of the pile, the stress on the side of the pile is different from that of the conventional pile. In this paper, according to different screw pitches, the failure modes of soil in different screw sections are proposed, and the calculation method of ultimate bearing capacity of screw pile under different screw pitches is obtained. Combined with practical cases and numerical simulation, it is found that the theory proposed in this paper is more practical.
