Fundamental Aspects of the Behavior of Saturated Soils UnderUndrained Cyclic Loads

现有的数据表明，任何一种药物的反应机制都是 土壤微观结构与荷载具有相同的关键组成部分，并且 主要得到了不同土的循环响应 因为在每种土壤中， 比其他人占优势。 因此， 不同的土壤可以联系在一起，并通过独特的解释， 这些微观结构机制，使土壤动力学更 严格而系统的纪律。 目前，没有这样的联系， 研究了有效土、无粘性土和粘性土 分别使用不同的循环特性， 土壤和循环土壤分类将根据 了解土壤微观结构的行为。

Available data indicate that the mechanism of the response of any soil microstructure to loads has the same key components, and that different cyclic response in different soils is obtained mainly because in each type of soil some of the components are more dominant than the others. Consequently, cyclic characteristics of different soils can be linked together and uniquely explained via these microstructural mechanisms, making soil dynamics a more rigorous and systematic discipline. At present, no such link is avialable, and cohesionless and cohesive soils are studied separately using differnt cyclic characterization of different soils and cyclic soil classification will be developed based on the understanding of the behavior of soil microstructure.
