摘要 螺纹桩基是一种新型桩基础,由于其具有较好的承载性能,已经在工民建、道路桥梁等领域有所应用,但是目前对螺纹桩的承载机理研究还不成熟。为了研究螺纹桩的承载机理及其承载能力计算方法,在前人研究工作的基础上,通过理论分析,探讨螺纹桩的竖向承载机理,分析螺纹桩尚未达到极限承载力时的承载能力计算方法,获得了螺纹桩不同桩段阻力和竖向极限承载力计算公式。为螺纹桩的进一步研究应用提供一定的理论支持。 As a new pile foundation, the crew pile has been used in civil engineering, roads and bridges, etc. because of its good bearing capacity, but recently the bearing mechanism of screw pile has not been studied deeply. In order to study the bearing mechanism and calculation method of bearing capacity of screw pile, under the foundation of previous research work, through theoretical analysis, we investigate the vertical bearing mechanism of the screw pile, analyze the calculation method of bearing capacity when the ultimate bearing capacity has not reached the ultimate capacity, and gain the calculation formula of the resistance of pile segment and the vertical ultimate bearing capacity, which provides a theoretical support for further study and application of the screw pile.
