桩基础抗拔承载特性研究

Research on Uplift Bearing Characteristics of Pile Foundation

为了解决地下空间的抗浮问题,针对抗拔桩基础这种新型基础形式,本文通过数字图像相关(DIC)技术及模型桩桩体的抗拔模型试验,对桩基础抗拔承载特性进行研究,可较好地弥补实际工况下试验难度大的缺陷,进而验证基础稳定性,为我国基础建设提供一定的参考依据。

In order to solve the problem of anti-floating in underground space,in view of the new foundation form of uplift pile foundation,this paper studies the uplift bearing characteristics of pile foundation through the digital image correlation(DIC)technology and the uplift model test of the model pile body,which can better make up for the defect that the test is difficult under the actual working condition,and then verify the foundation stability,providing a certain reference for the foundation construction in China.
