The Analysis for the Dynamic Strength and Vibration Liquefaction of Saturated Sand under Cyclic Loading

摘要

The liquefaction problem of saturated sand under cyclic loading is essentially a dynamic strength problems, but under the action of load, its strength has a sudden dramatic loss and it is unexpected, so it is different from the general dynamic strength problem. This paper analyzes the dynamic strength of saturated sand under cyclic loading. And its vibration liquefaction mechanism, influencing factors and preventive measures are analyzed and discussed.
