摘　　要：铀尾矿库的安全至关重要,铀尾矿的静动力学特性是进行尾矿库设计和安全分析评价的基础。以中国南方某铀尾矿库为研究对象,通过对现场钻探和室内试验数据进行函数拟合化和图像化分析,系统研究了该铀尾矿库地层的时空分布规律,以及密度、孔隙比、固结系数、渗透系数、内摩擦角、粘聚力、动弹性模量、动剪切模量、阻尼比等铀尾矿物理力学及动力特性的变化规律和内在机理,研究成果可为铀尾矿库的安全分析和安全运行提供指导。The safety of uranium tailings pond is especially important,while static and dynamic mechanical characteristic of uranium tailings is the basement of safety analysis and evaluation of tailings pond.This paper took one of southern uranium tailings pond as research target,and by means of function fitting and picturizing,systematically studied the regularity of space-time distribution of uranium tailings layers,as well as transformation law and inner mechanism of physical,mechanical and dynamic characteristic of uranium tailings,including indexes such as density,void ratio,coefficient of consolidation,filtration coefficient,internal friction angle,cohesion,dynamic modulus of elasticity,dynamic shear modulus and damping ratio.The result can provide an important guiding significance for the construction,operation and safety analysis of uranium tailings pond.
