“…Due to the new change of the current climate environment and the big scale of cold regions engineering, frozen soil mechanics research on new topics has many needs to be settled. Frozen damage mechanics research has obtained some new results in recent years [1][2][3][4]. Western of Liaoning offers a wide range of frozen soil .So in this paper, based on damage mechanics, using the dynamic triaxial test ,the frozen soil under dynamic load of damage evolution process is studied ,and the influence factors of damage evolution law are analyzed from two aspects in the frozen sand soil under dynamic load.…”

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 .
