FLAC3D, using the CaveHoek constitutive model, simulates the progressive failure and disintegration of the rock mass from an intact/jointed to a caved material. Open Access This is an open access article distributed under the CC BY-NC license ( ). FLAC3D has been widely used to simulate the in situ stress field in underground and slope engineering (Saati and Mortazavi 2011 Corkum et al. between the continuum code FLAC3D and the cellular automata code CAVESIM. In these models, the horizontal length and width of the fracture at the. The results showed that: There are relatively high stress concentration around roadway, especially on the left side and the roof, affected by space location during tunneling The vertical stress and the maximum and minimum principal stresses of roadway surrounding rock are increasing, while the horizontal stress is decreasing during the mining of working face During roadway excavation, Surrounding rock stress is asymmetry due to the asymmetry mining of near working faces and the multiple factors superposition affected by supporting pressure and original rock pressure, while both sides of the roadway are substantially symmetrical after the mining of working face. The proppants help keep the fracture open against the in-situ stresses trying to. APPENDIX D - SLOPE MODEL RUNS EXAMPLE FOR INCREASING PIT.
#Modeling horizontal in situ stress with flac3d software
Based on the linear function between the maximum horizontal stress obtained by fitting the measured in-situ stress test result and buried depth, FLAC3D software was used in this paper to analyze the characteristics of lower-group roadway surrounding rock under the influence of multi-mining of deep nearly interval coal seam. with in-situ stress magnitudes, with higher horizontal stresses resulting in increased fractur.
