Laboratory Model Test on Foundation Reinforcement by Locating Lime-Soil Pileat both Side of Strip Footing

Using similarity theory as guidance ,the paper designs the laboratory model test on foundation reinforcement by locating lime-soil pile at both side of strip footing, and researches foundation bearing capacity, p-s curve, the magnitude and distribution discipline of the foundation stress before and after reinforcement, and analyzes the load-bearing mechanism, strengthening mechanism and reinforcement effect of the strengthening technology. The results show that the lime-soil pile can effectively improve the foundation bearing capacity, and reduce the amount of ground settlement; under the role of the lime-soil pile, the stress spread lesser to the outside of pile in the ground, and causes the foundation stress to the deeper place.
