Experimental Research on Settlement Distribution of Composite Foundation Configured with Walled Soil Improvement

Abstract:

Because of the poor geological condition in the soft area, the bearing capacity of the ground is lower, which will cause large settlement of buildings. To cope with weak or compressible soils and control the differential settlement, the authors present a composite foundation system with net walled soil improvement. In this paper, the settlement of the composite foundations configured with different forms of walled soil improvement is studied by model tests. Through these tests, we see that the settlement in the center is much larger than that at the edge under uniform ground rigidity, and foundations differential settlement or settlement distribution is mainly decided by the rigidity and stiffness distribution of ground. If increasing the depth or area of walled soil improvement near the center of foundation, the differential settlement can be greatly reduced.
