介绍了普通克里金方法的基本原理,分析了岩体波速的空间变异特征,统计了岩体波速的概率分布特点,应用GOCAD软件对岩体波速进行三维空间插值,得到岩体波速的空间连续表达。研究表明岩体波速具有空间变异的特征,波速空间依赖性中等偏弱。三维可视化模型将岩体波速的空间分布可视化表达出来,以岩体波速三维可视化模型进行工程地质分析,使得地质解释可视化、定量化,提高了地质判断的准确性。
This paper introduces the basic principle of common kriging method, analyzes the spatial variation characteristics of rock mass velocity, and statistics the probability distribution of rock mass velocity. GOCAD software is used to interpolate the wave velocity of rock mass in three dimensions. expression. The study shows that the rock mass velocity has the characteristics of spatial variation, and the spatial dependence of wave velocity is moderately weak. Three-dimensional visualization model visualizes the spatial distribution of rock mass wave velocity and carries out engineering geology analysis based on three-dimensional visual model of rock mass wave velocity so that geological interpretation can be visualized and quantified, which improves the accuracy of geological judgment.
