    Experimental Investigation into the Influences of Weathering on the Mechanical Properties of Sedimentary Rocks by Xiaoshuang Li, Yingchun Li, Saisai Wu

    Published 2020-01-01
    “…The time-dependent behaviors of the sedimentary rocks which refer to the altering of the mechanical and deformable properties of rock elements in the long-term period are of increasing importance in the investigation of the failure mechanism of the rock strata in underground coal mines. In order to obtain the accurate and reliable mechanical parameters of the sedimentary rocks at different weathering grades, the extensive experimental programs including the Brazilian splitting test, uniaxial compression tests, and direct shear tests have been carried out on the specimens that exposed to the nature environments at different durations. …”
