Abstract
As a result of calculating bearing capacity of soft silt soil(ML) and soft silt soils(ML', SM, SM') mixed with sand, all kinds of soils showed smaller values than existing expressions and when theoretical values are applied, considerable review is required. It was found that ultimate surcharge(bearing capacity) of soft silt soil was $q_{ult}=1.34C_u$ that of ML' soil in soft silt soils mixed with 3 kinds of sand $q_{ult}=1.40s$, that of SM soil $q_{ult}=1.73s$ and that of SM' soil $q_{ult}=2.72s$, Consequently, as content of sand having greater permeability than silt soil in creased, soil was stabilized gradually.
