摘要

现浇薄壁管桩（Cast-in-place Concrete Thin-wall Pipe Pile

简称PCC桩）作为一种新型桩基础，已在很多地基处理工程中得到应用，但有关其水平承载性的研究还很少。通过现场试验，对水平荷载下PCC桩的水平承载性、泥面处桩荷载-位移关系、桩周土压力变化以及桩侧地基水平抗力系数的比例系数m与位移关系等特性进行初步分析，同时对单向多循环加载和慢速维持荷载两种加载方式对桩受力特性的影响进行比较。试验表明，PCC桩有较好的水平承载性，在水平荷载下，PCC桩的受力主要集中在桩的上部；与慢速维持荷载法相比，单向多循环法对桩的水平承载性以及桩土作用的非线性影响较大。

Abstract

As a new kind of pipe pile

the cast-in-place concrete thin-wall pipe pile

referred to as PCC pile

with a large diameter

has been used in many engineerings to improve the soft ground; but the bearing capacity under lateral load hasn’t been studied well. Through the in situ test

the authors analyze the horizontal bearing capacity

the pile displacement and the soil pressure around the pile under lateral load. In addition

the effect of the repetitious loading pattern on the pile-soil interaction is also given. All tests show that the PCC pile can be provided with preferable horizontal bearing capacity; and the force act on the PCC pile mainly fast on the upper part; at last

the analysis also shows that the one-way cyclic loading has much effects on pile lateral capacity and the nonlinearity of pile soil interaction.
