Abstract:

Rock joint is the basic for studying the physical and mechanical properties of rock mass structure surface，but it is difficult to fully understand the rock joint distribution patterns in space，owing to deep buried in the rock mass.To show the development characteristics of rock joint in three-dimensional space and master the distribution regularity of joint fissure in rock mass，the distribution model of rock mass joint in three-dimensional space was constructed.Taking Panlong lead-zinc mine in Guangxi as the research object，the basic information of rock joint in the field was obtained by means of line method，and the parameter distribution probability model was determined by using the theory of probability and mathematical statistics to analyse the joint geometry parameters.According to the principle of Monte-Carlo simulation and the relevant function of Excel to produce random number，the simulation data was obtained，and then based on the AutoLISP language simulation program，3D-network simulation visualization of rock joint was generated in CAD，and it will be applied to rock mass quality classification in the model.Research shows that the joint plane three-dimensional network simulation effect is good，in the rock mass quality evaluation fully embodies the opposite sex characteristics，the evaluation results tend to be more practical，this method provides a new idea and way for the study of rock joints.
