LIQUEFACTION OF RED RIVER SAND SUBJECTED TO UNDRAINED CYCLIC LOAD

Abstract

Study on liquefaction possibilities of Red river sand locating near the Hanoi port has been conducted using a series of undrained cyclic triaxial tests. The test results have shown that it is possible to determine effectively the liquefaction characteristics such as excess porewater pressure, axial strain variation, cyclic ratio with the cyclic number causing the specimen to be liquefied. The test results will be useful for the prediction of liquefaction caused by earthquake for the Red river sand.
