Abstract

Economy and environmental safety have recently become very important factors in the construction of soil structures. A combined technology of shallow stabilization and floating-type cement treated columns has an advantage to reduce the construction cost of the soil structure on deep soft soil layers. In this study, at first, skin friction around the surface of the column was investigated by the one dimensonal consolidation tests. Secondly, loading model tests were conducted under the plane strain condition in different improvement conditions to investigate failure tendency of the improved ground. Finally in order to evaluate bearing capacity of the improved ground, equivalent conversion model is proposed with consideration of skin friction. It was confirmed that the bearing capacity can be estimated by using this proposed model.
