摘要
离心模型中的固结时间是原型的固结时间缩短至1/N2,能够在较短的时间内模拟软土地基的长期沉降.采用离心模型试验方法,模拟软土地基在粉喷桩处理后的渗透固结性状。通过对地基施工期阶段及工后的沉降进行分析,证实了用粉喷桩进行处理地基是可行的。
Centrifugal physical model test can shorten the consolidation time to 1/N^2 of the prototype permeation and consolidation of clay foundation disposed by jet - grouting pile. In this paper, authors use the centrifugal physical model to estimate settlement of the soft foundation and compare the modeling results with field observation of settlement during construction and post- construction.
