Abstract EN
The strength of crumb rubber mortars can be improved by the addition of basalt fibers.
However, limited studies have been conducted on basalt fiber crumb rubber mortars (BF-CRM), and the constitutive model is still very immature.
In this paper, uniaxial compressive stress-strain curves are obtained for several groups of BF-CRM specimens with different contents.
By comparison with the GZH model, modified GZH parameters that can be used in a BF-CRM constitutive model are obtained.
Then, taking the support scheme of the main substation of a mine as the background, FLAC3D is used to simulate the roadway support, BF-CRM replaces the ordinary mortars in the original support, and triaxial compression tests are performed at different confining pressures.
In this way, the application of BF-CRM in roadway support is studied and analyzed.
