摘要

The purpose of this paper is to investigate the features of a jet grout arch under vertical load. With the help of an in situ load test of the arch-like shell created by horizontal jet grouting, the vertical and horizontal displacements of soil-cement columns were separately measured, and the deflections and the failure patterns of the jet grout arch were analyzed in our experiment. Furthermore, a numerical comparison by ADINA FEM analysis was achieved, which indicated a good similarity between test and numerical results.
