摘要/Abstract

摘要： 岩体不连续面迹长、产状、空间组合形态等的不确定性和复杂性，使结构面整体几何形态研究存在困难。利用岩体内大量随机展布的不连续面所具有的统计相似性，结合具有统计意义的数学方法进行结构面参数描述，是岩体随机不连续面三维网络模拟的基础，也为岩体稳定性评价提供可靠依据。本文基于数字近景摄影测量技术对长春市净月开发区东升采石场坡面进行调查研究，获取高精度的大量岩体结构面迹长、产状、间距、张开度等几何参数。利用Matlab编制Kolmogorov-Smirnov（K-S）检验程序，实现结构面参数的K-S法概率分布检验，分析了结构面参数所服从的概率分布类型；同时用SPSS软件检验程序正确性，并引入最优拟合度，选取符合多种概率分布参数的最优拟合概率模型。结果表明：研究区内结构面迹长、间距服从对数正态分布规律，产状服从伽马分布规律。

Abstract: The uncertainty and complexity of rock discontinuities such as trace length, occurrence and spatial combination form make it difficult to study the whole geometry of structural plane. The discontinuous surfaces with large number of random distributions in rock mass are statistically similar. Using statistical methods to describe the structural plane parameters is the basis for 3D network simulation of rock random discontinuities, and it can also provide a reliable basis for stability evaluation of rock mass. Based on the digital close-range photogrammetry technology, the slope of Dongsheng quarry in Jingyue Development Zone of Changchun City was investigated and studied, and a lot of high precision rock mass structure details were obtained such as long trace occurrence, spacing, aperture geometry parameters. We compiled the Kolmogorov-Smirnov (K-S) test program by Matlab to test the probability distribution of the structure parameters, analyzed the structure parameter types of probability distribution, used SPSS software to test the correctness of the program, and introduced and selected the optimal fitting probability model which accords with a variety of probability distribution parameters. The results show that the length and spacing of the structural surfaces in the study area obey the lognormal distribution, and the shape of the structure obeys the Gamma distribution.

Key words: close range photogrammetry, structural surface parameter, K-S method, probability distribution, fitting test
