摘要： 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。

Abstract: This paper introduces the basic principle of the application of the ordinary Kriging method in estimation of the wave velocity and its space variation characteristic of the rock mass. The probabilistic distribution of the rock mass wave velocity are statistically studied. The wave velocity of the rock mass are three dimensionally interpolated by using the GOCAD software so that the space variation of the wave velocity in the rock mass are obtained. The results indicate that the rock mass wave velocity has some medium to weak space variation. The three dimensional visualization of the wave velocity in the rock mass can provide quantitative and visual solutions for the geological material and can also improve the accuracy of the engineering geology analysis.

Key words: Rock Mass Wave Velocity, Spatial Variability, Ordinary Kriging Method； 3D Visualization, Quantitative Evaluation
