摘要
三相饱和土是由固体土颗粒、水和少量封闭气体组成的混合物介质。在爆炸压缩波荷载作用下 ,三相饱和土极有可能液化 ,这主要与孔隙流体与土骨架动力响应之间的差异有关。从微观力学角度着手 ,通过选取适当的坐标系 ,明确各相间相对运动和变形的物理意义 。
Three phase saturated soil consists of solid particles, water and a small amount of trapped air. It is prone to be liquefied under blast compressive wave loading, mainly because of the difference between dynamic responses of pore fluid and the solid skeleton. The theoretical model of blast induced liquefaction was constructed herein on the basis of micro mechanics, in which the small strain limit was removed, and the inertial effect and the interaction between pore fluid and solid phase were both included. The study is carried out within 3 dimension space.
