Abstract

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.
