2016-9-9  Deep mixed columns are similar to stone columns. They reduce expected settlement by promoting soil arching which transfers the loads to stiffer panels rather than insitu soil. But the main difference between them is that strength of stone columns is dependent on the friction angle of the aggregate and confinement from surrounding soils; while deep mixed columns have internal strength from cohesion. Deep mixed columns are constructed such that they are continuous panels and the groundwater flow will be reduced.
