Abstract

Abstract

Ring-reinforced lime-soil piers could be used to treat collapsible loess and soft soil foundation. Modulus calculation method is an important factor in engineering design. The deformation characteristics and failure mode of ring-reinforced lime-soil piers were analyzed by numerical method. The influence of confining pressure, the characteristics of lime-soil pier and the properties of ring-reinforced materials on the deformation characteristics of ring-reinforced lime-soil piers were studied. Considering the lateral restraint effect of reinforced materials, the calculation method of elastic modulus was deduced. By comparing the theoretical and numerical results, the theoretical calculation method for the elastic modulus of reinforced lime-soil pier was modified. The research results could provide a theoretical method and basis for engineering design.
