|
摘要
指出冻土动态力学特性主要研究在各种动态荷载作用下冻土的变形和强度特征及土体稳定性,其研究成果对寒区工程设计有着重要的意义,主要从动力学参数、动应力应变关系及动强度、动蠕变等几个方面介绍目前冻土在动态荷载作用下的力学特性的研究状况并进行了分析。
The paper mainly introduces the main research on the dynamic characteristics of freezing soil,the deformation and strength characteristics and soil stability under all kinds of dynamic loading effect,and its research is meaningful for the project design in cold areas.Besides,the paper also indicates the research situation for the dynamic characteristics of the freezing soil under the dynamic loading effect by the introduction on the dynamic parameters,the dynamic stress-strain relationship and dynamic creeping.
