摘　　要：应用赤平极射投影原理研究节理统计的程序化算法,其中采用Multiquadric方法建立原始节理数据三维模型和加权法计算优势方位。为便于在工程实践中快速识别节理化岩体结构,根据上述算法应用基于COM技术的MATLAB和VB混合编程方法开发节理统计分析程序。对厦蓉高速公路水都线现场测量数据进行分析,结果表明:该程序能实现优势结构面自动分组和信息统计。A computer algorithm of joints statistics was studied based on stereographic polar projection principle, with the three - dimensional model of the field data reconstructed by using multiquadric method and the dominant orientations calculated by using weighted distribution method. For the purpose of recognizing the structure of jointed rock mass and application in engineering practice , a program of joints statistics and analysis was devel- oped by using mixed -language programming between MATLAB and VB based on component object model （COM）. Analysis of the field data of Xiamen- Chengdu Highway shows that the program can be used in automatic distribution of discontinuities and has a high accuracy and value in application.
