摘要
Y形沉管灌注桩是在传统沉管灌注桩的基础上研制出的一种新型沉管灌注桩,2003年首次在申苏浙皖高速公路工程中被应用于桥头段深厚软基的处理。本文介绍了申苏浙皖高速公路工程中Y形桩试验段的桩土应力、桩土表面沉降、分层沉降、侧向变形、孔隙水压力等项目的现场观测成果,并对路堤荷载作用下Y形沉管灌注桩加筋路堤的性状及其处理效果进行了分析。
Y-shaped vibro piles were special vibro-piles applied in Shen-Su-Zhe-Wan Expressway to improve soft clay ground in 2003. Based on the field tests on Y-shaped vibro piles, the stress of piles, settlement, lateral displacement and pore water pressure of soil were presented. The performance and feasibility of the Y-shaped vibro piles were discussed in detail.
