摘要
                
                    从冻土微观结构分析了其冻胀、融沉发生机制,结果表明:随着温度的变化,冻土会出现冻胀和融沉现象,这些破坏的出现与其微结构随温度的变化密切相关,温度的变化诱发微结构内部颗粒间连接刚度的变化,正是这些变化导致了冻胀、融沉现象的出现。
                
                By analyzing the mechanisms of the thaw and frost heave of frost soil, the author found that when the temperature arises, the frost soil will have the thaw and frost heave, which can make great disasters and are closely related to temperatures. Changes in temperature can change the coupling stiffness between the micro-particles and then lead to these harmful phenomenons.
