| 摘 要： | 在我国大渡河流域广泛分布一套规模巨大,形成于第四纪更新世中晚期的冰水堆积体.这类冰水堆积体在颗粒组成、结构特征、密实程度等诸多方面与其他松散堆积体存在较明显的区别,因而其变形特性、强度特性等方面与其他岩土体相比,也表现出较为明显的差异.以大渡河某巨型冰水堆积体为例,在室内大型常规三轴试验的基础上,对该冰水堆积体的变形特性、强度特性进行了较为深入的研究和探讨,结果表明该冰水堆积物在剪切破坏过程存在较明显的应变强化和剪胀现象,其强度包络线在低应力水平下呈直线状,在高应力水平下呈非线性下凹形,由此提出了应力水平与抗剪强度参数的试验关系式.

| Abstract: | There are a lot of outwash deposits which were formed in the medium-term or terminal Pleistocene of the Quaternary Period distributed along the upriver valley of Daduhe river,these outwash deposits are different from some ordinary incompact deposits in structure,components and other facets,and therefore the strength and deformation behavior of the outwash deposits is different from that of other incompact deposits. In this paper,based on large-scale triaxial tests,we have studied an huge outwash deposits' d... |
