近年来,国际上广泛开展岩石流变学研究,模拟岩石在地壳内的物理状态和破坏过程,以寻求地球动力学及地震等灾害性地质现象的物理基础。时间是流变学研究中非常重要的参数。同一物体,在相同的温度、压力条件下,表现的流变特征依赖于所持续作用的时间。岩石材料单轴高温蠕变装置,正是为了研究在长期稳定压力和高温环境下,岩石变形和破坏过程随时间的变化这一目的而设计制造的。目前,国际上进行岩石蠕变试验的手段、形式不一,但绝大多数是利用丝杠或液压加载方式。这种加载
In recent years, rock rheology has been extensively studied in the world to simulate the physical state and destruction process of rock in the crust so as to seek the physical basis of disastrous geological phenomena such as geodynamics and earthquakes. Time is a very important parameter in the study of rheology. The same object, in the same temperature and pressure conditions, the rheological characteristics of the show depends on the duration of the sustained effect. The uniaxial high-temperature creep device for rock materials is designed to study the purpose of the rock deformation and failure process over time under long-term stable pressure and high temperature conditions. At present, the means of rock creep test in the world are different, but most of them use the screw or hydraulic loading method. This loading
