Abstract Because that it is hardly applicable for mechanical analysis of rock mass currently，equivalent rock mass model，which is constructed to reflect actual space status of joints，is the research foundation for stability analysis of rock mass engineering. Taking Baiyunebo eastern iron open pit in Inner Mongolia as research background，based on the field joint investigation by scanline，the dip direction，dip angle，spacing and trace length of field joints are statistically analyzed with bias correction；and then their corresponding probability distribution models are established by using probability statistics theory. Based on these work，Monte Carlo stochastic simulation theory and Matlab software are adopted to obtain simulated joints data. Based on OPEN GL technique，these data are then used to construct visual stochastic joints 3D-network model of equivalent rock mass，which reflects the distribution feature of field joints. The simulation result shows excellent statistical similarity with the measured data. These research achievements can be utilized by equivalent rock mass technique，and can lay a foundation for following quantitative research of rock mass property，such as deformation，strength，size effect，anisotropy，representative elemental volume(REV)，key block identification，excavation effect and fracture mechanism.

Key words： rock mechanics stochastic joints 3D-network model of equivalent rock mass equivalent rock mass technique probability statistics Monte Carlo stochastic simulation
