DEEP STABILIZATION OF SOFT COHESIVE SOILS

This report presents a new method for improving the bearing capacity and shear strength at relatively large depths of soft cohesive soils, mainly clay. A stabilizing agent, mainly unslaked lime, is forced down to the desired depth and mixed with the soil by a rotating auger or by a tool formed in the shape of a giant egg whisk. Thus relatively uniform columns of stabilized soils are formed in the ground with the same diameter as that of the auger. In this way foundations for buildings and other structures are safer and less expensive to construct in comparison with other foundation methods. The method has been tested, and results obtained so far indicate that the stabilized columns appreciably reduce the total settlements and almost entirely eliminate the differential settlements. /TRRL/
