Back calculation of modulus of deformation and bearing capacity for foundation after dynamic consolidation

In this paper,through establishing model of back analysis,the modulus of deformation for foundation after dynamic consolidation can be determined by single valued back analysis method, in which the settlement modulus of deformation curve and the final drop settlement for control of soil densification are used.Based on the basic theory of plate loading test,the allowable bearing capacity can be predicted by the relative settlement ratio method. Many practical examples of calculation show that the calculated results can satisfy the engineering demand and have high reliability.Therefore,a new method is provided to predict the improvement effect, to check the rationality of orignal design and to improve the design for dynamic consolidation.
