Wetting characteristics of coarse-grained materials

  • 摘要: 采用大型三轴仪,对花岗岩和变质岩两种堆石料,比较系统地进行了单线法和双线法湿化试验。依据试验成果,比较了单线法和双线法试验成果间的差异,明确了堆石料湿化特性试验研究宜采用单线法,确定了单线法湿化变形取值方法,比较了不同堆石料湿化变形规律,得到了堆石料湿化应变与应力状态的相关关系,初步提出了堆石料湿化模型及模型参数。提出的堆石料湿化模型及参数可作为堆石坝湿化变形分析的基础。
    Abstract: Based on single-line method and double-line method, wetting tests on two kinds of coarse-grained materials, granite and metamorphicrock, are performed by use of a large-scale triaxial apparatus. According to the test results, there are some differences between the single-line method and the double-line method. The single-line method is better to study the wetting characteristics of coarse-grained materials. The method to obtain the wetting defomation in the single-line method is established. Based on different wetting deformation regularities of coarse-grained mateials, the relationship between strain and stress in the wetting tests is obtained. As a result, the wetting model and model parameters of coarse-grained materials are proposed and used as the basis in the analysis of wetting deformation of coarse-gained materials.
