Analysis of the Damage Evolution Characteristics of Liaoxi Frost Sandy Soil on Dynamic Load

Abstract:

To analyze the damage evolution characteristics of Liaoxi frost sand soil on dynamic load , firstly in the foundation of frozen soil damage theory,micro-strength and dynamic modulus are introduced to analyze the damage evolution characteristics of Liaoxi frost sandy soil .Then ,based on the dynamic triaxial test ,respectively analyze the influences made to dynamic modulus by confining pressure and initial water content . Some regular patterns are summarized .The greater the confining pressure, the greater the dynamic modulus of frost sand soil is ,and with the increase of dynamic strain the dynamic modulus under different confining pressure trend to be same .The bigger quantity of initial water content ,the greater the dynamic modulus is and the change rate of frost sand soil`s dynamic modulus with different initial water content are approximately equal .That initial water content has more significant effects on the dynamic modulus is found by the comparison of the effects caused by confining pressure and initial water content .
