摘要

摘要: 通过对浙江温州软土地区防洪堤工程中的同一场地PHC管桩和预制方桩的现场静载对比试验,比较了两类桩型的预制桩的荷载-沉降曲线、桩身轴力分布情况、桩侧摩阻力分布等特性的异同。试验结果显示,当桩侧表面积相近且桩长相同时,软土地区中的预制方桩和PHC管桩在工作荷载作用下的桩身轴力、桩侧摩阻力、桩端阻力虽然表现规律较类似,但是其发挥的程度并不同。

Abstract: Based on the static load tests on pretensioned high-strength concrete piles (PHC pipe) and precast square piles in the same test field of soft soil area of Wenzhou flood dike project in Zhejiang Province, the load-settlement curves, shaft load distribution curves and behaviors of skin resistance of these two types of piles are compared. The experimental results show that, for the PHC pipes and precast square piles with the same lateral area and pile length in soft areas, the behaviors of skin resistance and base resistance are different, although their axial forces, lateral friction forces and base resistances appear closely similar.
