Pile-soil Stress Ratio of Pile-supported and Geogird-reinforced Composite Foundation
The load and deformation of the pile-capped horizontal reinforced cushion of the pile-supported and geogrid-reinforced composite foundation were discussed to obtain the deformation and the tension stress of the reinforced material. Treating the pile and the soil as linear elastic object, and considering the static equilibrium and the compatibility of deformation as well as the influence of the reinforced material, the calculation method of the pile-soil stress ratios in different depths of the reinforced material was deducted. This method takes the following influence factors into account: differential settlement between pile and soil, horizontal reinforced cushion, pile distance, diameter of the pile cap and so on. Finally, to validate the proposed method, a case study was illustrated, which shows that the calculated value is close to the observed value. The pile-soil stress ratio and the bearing capacity of the composite foundation will be higher after setting up the horizontal reinforced mattress. This method is feasible for calculating the pile-soil stress ratio of the pile-supported and geogird-reinforced composite foundation.
