THE INFLUENCE OF LOADING FREQUENCY ON DYNAMIC SUBSIDENCE PROPERTIES OF SAND IN ANISOTOROPIC CONSOLIDATION CONDITION

Abstract

 There are many studies on the liquefaction properties of sand in isotropic consolidation condition, and various things have been revealed. The influence of loading frequency on liquefaction properties of sand is one of them, and it concluded that the loading frequency does not affect the liquefaction properties of sand in laboratory test. However, the ground under the structure or embankment is in anisotropic consolidation condition with constant deviator stress during an earthquake. And the studies on the liquefaction properties in such condition are few, and the influence of loading frequency is still unrevealed.
 In this study, the influence of loading frequency in such condition was investigated by torsional hollow cylinder shearing test. The test results indicate that the loading frequency affects the increase in axial strain of the ground in anisotropic consolidation condition.
