Outline of Final Research Achievements |
The generalized scaling laws for bending moment, acceleration and pore pressure are validated through the shaking table tests of various centrifugal acceleration levels. A limitation was revealed when the small centrifuge acceleration is used (4.9g) which causes a low level of confining stress. Comparison of the results of identical experiments among several research institutes showed some variations of lateral deformation of the liquefied ground because of difficulties associated with generating the identical input motions. Overseas collaboration (UK, USA, China, Taiwan, Japan) was established to conduct the identical experiments and compare results in the workshop held in Washington DC in 2015. In the workshop, causes of variation observed in the test results were clarified and procedure to have better agreements among test results were discussed for the future collaboration. Details of the experiments and their results are under publication.
