Experimental investigation on uniaxial compressive mechanical characteristics of red-sandstone containing single fissure after rainfall infiltration

Abstract: The fissure flawed red-sandstone under dynamic rainfall infiltration is one of the key factors determining the safety and reliability of red-sandstone embankment and slope. However, there is still a lack of investigations considering the combined influence of rainfall infiltration and flaw geometry on the mechanical behavior of fissure flawed red-sandstone. Therefore, the effects of rainfall intensity, rainfall duration, as well as prefabricated fissure inclination angle on the uniaxial compressive mechanical … Show more

“…As sedimentary rock, red sandstone is widely distributed in underground rock formations such as tunnels (roadways) surrounding rocks and coal roof slabs. With the exploitation of resources and construction of underground projects, mechanical behaviour problems associated with red sandstone have been increasing in recent years, such as rockbursts, spalling, fracture, and weakening of rock strength (Yang et al 2012(Yang et al , 2013Luo 2020;Chen et al 2021;He et al 2021;Jiang 2021;Li et al 2021;Tang et al 2021;Wang et al 2021;Xu et al 2021). Therefore, to evaluate the rockburst proneness of rock with prefabricated borehole, fine-grained brittle red sandstone specimens with different prefabricated borehole arrangements collected from Junan County, Shandong Province, China were selected for tests (Figure 2).…”
