三维可视化建模技术在岩体质量评价中的应用

 岩体的结构特征对岩体工程施工有着重要影响，因此，正确进行岩体质量评价对工程设计和建设具有十分重要的意义。通过对大量数据的采集分析，运用三维可视化工程软件，以一种新的数据结构和方法建立工程结构和地质体三维线框和块段模型，并采用地质统计学方法对三维地质块段进行质量评价指标有效估值，最后按照空间图形集合运算算法，将不同指标的块段模型合并到一起，对岩体质量进行分析评价。将上述理论方法应用到金川III矿区的矿岩可崩性研究中，获得良好的应用效果。

APPLICATION OF 3D VISUALIZATION MODELING TECHNOLOGY TO ROCK MASS QUALITY EVALUATION

The structural characteristic of rock mass plays an important role in rock mass engineering construction，so correct evaluation of rock mass quality is of great engineering significance. Based on the collection and analysis of massive data，taking advantage of 3D visualization engineering software，3D engineering rock mass and block models are reconstructed by means of a new data structure and method. Then，effective estimation of 3D geological block models is made by geological statistics. Finally，block models with different indexes are combined using set operation algorithms of space pattern so as to analyze and evaluate rock mass quality. The theory is applied to rock mass quality evaluation in the third mining zone of Jinchuan mine with satisfying application efforts.
