Model Testing of Encased Stone Column Composite Foundations under Traffic Loads

In soft soil foundations, geogrid encased stone column composite foundation technology has been widely applied and developed in recent years due to its efficient treatment. this study, eight groups of laboratory model tests were performed a large-scale testing tank investigate the bearing mechanism stress characteristics columns under traffic loads with different cyclic load ratios. The at bottom settlement measured analysed. test results show that shearing will cause rearrangement particles column-soil interface, which changes face pressure effective state boundary. substantial influence on accumulation development lateral column. Based results, law cumulative is summarized, change analysed discussed.
