GEOTECHNICAL INTRODUCTION TO SOIL STABILIZATION AND REINFORCEMENT

GEOTEKNISK INTRODUKTION

The trafficability of vehicles on a ground surface depends on three factors: the rolling resistance, the traction and the bearing resistance. All factors are dependent on the geotechnical conditions. When the subsoil consists of organic material or soft clay special methods often have to be used in order to ensure the bearing resistance. The method usually involves load distribution (reduction of the shear stress in the soil) and/or increase of the shear strength of the soil material. The shear stress in the soil can be kept at a low level by the use of vehicles with wheels or tracks with large dimensions. Low shear stress levels can also be achieved by embankment constructions involving load distribution or horizontal reinforcement. The shear strength in the subsoil and in the embankment fill can be increased; non-cohesive soil by compaction, fines by stabilization with cement or lime. By the lime column method clay soil can be stabilized down to a depth of several meters. (TRRL)
