Centrifuge modeling of soil response by low energy dynamic compaction

in order to demonstrate the suitability and the repeatability of the WAK test i.e. the ability to predict the increase in mechanical propertise of soil; stiffness(K), damping factor (C), mass of vibrated (M) and depth of improvement (D) with increasing number of blows, the results of three centrifuge tests are presented. the results show that the behaviour of the soil system is similar in each case with an increasing number of blows. in order to measure the soil dynamic response during each blow, an array of earth pressure cells were placed within the soil mass. the compression strees weve(P-wave) velocity was determined frim examinatin of the difference in arrival times at dynamic earth pressure cells located in the soil.
