LEAP-ASIA-2019: Summary of Centrifuge Experiments on Liquefaction-Induced Lateral Spreading – Application of the Generalized Scaling Law
摘要
In the framework of Liquefaction Experiments and Analysis Projects (LEAP), round-robin centrifuge model tests were conducted in collaboration with ten international institutes on identical saturated sloping sand layers with a wide range of initial conditions. Two tests, one with a model following conventional centrifuge scaling law and the other with a model following the generalized scaling law (GSL), were assigned to each institute for two purposes: (1) validation of the generalized scaling law (GSL) and (2) development of additional experimental data sets to fill the gaps in the existing experimental data sets. The GSL may be validated when the ground deformation is small (less than 250 mm in the present study). The trend surface was updated with the new data sets, whose trend is consistent with the previous one.
