Abstract: The mechanical characteristics are analysed based on compression test,shear test,tensile test,extraction test of soft soil reinforced by geogrid. Through laboratory model tests, the following studies are performed: the lateral and vertical displacement of the variation with depth,displacement field, stress field, strain field of the foundation reinforced and non-reinforced by geogrid. The results show that it is feasible to change and to resist the formation and development of plastic zone; the influence of reinforced cushion to spread and even up distribute stress of soft soil of substratum, and as well the role of geogrid, to control plastic deformation, to strengthen ductility and stiffness, to decrease lateral and vertical displacements, to strengthen shear strength of soft soil foundation, to improve the stability of the foundation and bearing capacity of reinforced soft soil; the study provides reliable basis for engineering applications.

Key words: geogrid, soft soil foundation reinforcement, model test, displacement field, stress field, strain field
