CENTRIFUGAL TEST USED TO DETERMINE PERFORMANCE OF DISPOSING CLAY FOUNDATION WITH JET-GROUTING PILE

Centrifugal physical model test can shorten the consolidation time to 1/N2 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.
