摘　　要：挤扩支盘桩是一种新桩型,其承载能力和抗沉降变形性能远优于等直径桩,具有良好的经济和社会效益。在已有研究的基础上,利用数字图像相关技术(DIC)对模型试验各阶段的数码照片进行相关性分析,得到竖向荷载作用下挤扩支盘桩的桩周土体位移场及其破坏性状。The squeezed branch pile is a newly invented pile foundation in recent years. Compared with the equal-diameter pile, it is much better with higher bearing capacity and less settlement and thus it has good economic and social benefits. Based on the previous research and DIC-related technique, this paper makes a correlation analysis on the series of digital images in every phase and presents the displacement field of soil around the squeezed branch pile and the failure pattern of pile.
