Soil-Cement columns bearing capacity: static load tests

Abstract

This communication presents the results of four static load tests carried out on Soil-Cement columns realized using the wet Deep Mixing Method. After a short introduction, the geological and geotechnical context is presented, as well as the tool used to execute the columns. The instrumentation is then described into details. Then, the main results of the four load tests are presented, such as the bearing capacity and creep load. The base resistances and shaft resistances derived from the extensometers installed in the columns are then pared to each other. Finally, results are compared to past experiences realized in soils of comparable nature, and to calculated values according to different standards.
