Initial Earthquake Centrifuge Model Experiments for the Study of Liquefaction

摘要

This project is a continuation of earlier research work by the Principal Investigator in support of the Earthquake Engineering Research Program, under the direction of the USAE Waterways Experiment Station at Vicksburg, Mississippi. The report describes the initial experiments in the program of studies planned under the EERP. These are intended to gather data suitable for the development of improved design approaches for the prediction of liquefaction under earthquake loading using the new centrifuge facility at the WES. A detailed experiment program has been developed for the first series of experiments studying the development of excess pore pressure in a level saturated sand bed under dynamic shaking at different effective overburden stresses. The initial experiments using the new large 'earthquake' shaker have been completed and data is presented and analysed.
