摘要
流变特性是软岩固有的属性 ,在长期荷载作用下的软岩巷道支护设计必须考虑岩石的流变特性。针对“三软”煤层巷道围岩大变形、难支护的具体情况 ,以显德汪矿的主运输大巷为研究对象 ,进行了三轴压缩流变试验 ,获得了泥岩的流变参数 ,从而为下一步的软岩巷道支护设计、施工提供了科学的依据。
Rheological characteristic is the intrinsic one of the weak rock and the rheological characteristics have to be .considered in design of the weak rock tunnel. Due to the large deformation and difficult supporting of weak rock tunnel, taking the main tunnel of Xiandewang coal mine as an example, a rheological test has been done and the rheological parameters of mudstone have been obtained. Moreover, the direct scientific ba sis was provided for the weak rock tunnel support.
