Based on the FLAC3D numerical software, a roadway excavation and support model was established. The stability of surrounding rock FRP bolt force characteristics in Yuhuasi mining area Jinshandian Iron Mine were analyzed. distribution law plastic zone simulated, deformation simulated. data for 6 months tested site, weak links determined, optimized. Parameters, optimized effect is better, which p...

Uniaxial compressive stress-strain curves of several groups basalt fiber crumb rubber mortars (BF-CRM) with different contents are tested. By comparing the GZH model, improved values parameters BF-CRM constitutive model based on obtained. Then, taking supporting scheme main substation mine as background, using FLAC3D to simulate roadway support, replace ordinary in original and combining triaxi...

There are few calculation methods for the design and construction of vacuum preloading to strengthen soft foundations. Based on FLAC3D, a model was established project Beijing–Shanghai high-speed railway. Through comparison measured values, following results were obtained: (1) The top surface reinforcement area sand drain can be regarded as load boundary, which realized by assigning node pore w...

In this study, based on the engineering background of No. 8222 working face Tashan coal mine in Shanxi Province, China, true triaxial experiments were carried out Geotechnical Consulting and Testing Systems rock mechanics testing machine using cubic samples, numerical simulation was conducted through FLAC3D software. Moreover, stress evolution law different layers extra-thick seams failure mech...
