摘要:

岩体节理是研究岩体物理力学性质的基础,但其通常深埋在岩体内部,很难全面了解其空间分布形态。为展现岩体节理面在三维空间的发育特征,掌握节理裂隙在岩体内的分布规律,构建岩体节理面三维空间分布模型。以广西盘龙铅锌矿为研究对象,采用测线法获取现场节理基本信息,运用概率论与数理统计对节理几何参数进行统计分析,并确定参数分布的概率模型。根据蒙特卡洛模拟原理结合Excel中产生随机数的相关函数,获取模拟数据,利用AutoLISP语言编写模拟程序,在CAD中生成三维节理面网络模型,并将该模型运用到岩体质量分级中。研究表明:节理面三维网络模拟效果良好,在岩体质量评价中充分体现了各项异性特征,评价结果更符合实际,该方法为岩体节理面研究提供了一种新的思路与途径。

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.
