Abstract
Soil strain is the key parameter to control the elasto-plastic deformation and even the failure processes. To overcome the defect that the strain of the model soil is always smaller than that of the prototype in Iai’s generalized scaling law (GSL), a modified scaling law was proposed based on Iai’s GSL to secure the same dynamic shear strain between the centrifuge model and the prototype by modulating the amplitude and frequency of the input motion at the base. A suite of dynamic centrifuge model tests of dry sand level ground was conducted with the same overall scaling factor (λ=200) under different centrifugal accelerations by using the technique of “modeling of models” to validate the modified GSL. The test results show that the modified GSL could achieve the same dynamic strain in model as that of the prototype, leading to better modeling for geotechnical problems where dynamic strain dominates the response or failure of soils. Finally, the applicability of the proposed scaling law and possible constraints on geometry scaling due to the capability limits of existing centrifuge shaking tables are discussed.
