| 摘 要： | 土体是一种具有特殊结构的微观介质 ,基于土体的微观结构特性提出了一种新的土体结构模型---随机土体结构模型以及随机土体结构模型的四条基本假设 ;根据四条基本假设 ,构造土体的微观结构网络 ;利用这种结构网络进行数值计算 ,可以较好地模拟土体的力学性状。最后 ,利用该模型从土体结构破坏的角度解释了砂土液化的过程和现象

| Abstract: | Soil is a medium with microstructure made of particular frame. This paper presents a new model,random soil frame model,according to the microcosmic soil frame and brings forward four basic hypotheses of this model.Based on the four basic hypothesis, the microcosmic soil frame network is obtained. With the numerical calculation of the microcosmic frame network, the mechanical properties of soil can be well simulated. Finally, by means of this model, the process and phenomena of the soil liquefaction is explained in the light of soil frame failure. |
