摘要: 岩体随机不连续面三维裂隙网络模拟是近年来一项评价岩体结构特性的重要手段,但该模型中并未考虑裂隙宽度对岩体稳定性的影响.对辽阳石门硅石矿岩质边坡的裂隙进行了现场不连续面窗口调查,利用卡方检验、K-S检验相结合的方法,对所统计的裂隙宽度进行概率统计分析,从而选取最佳概率分布类型.统计分析结果表明,辽阳硅石矿岩质边坡裂隙宽度分布多呈伽马型分布函数,小于10mm宽度的裂隙占大多数,构造应力类型对裂隙宽度分布参数起主要影响,可为三维裂隙网络宽度模拟提供理论依据.

Abstract: Three dimensional network modeling technique for random discontinuities of rock mass is a significant method to evaluate the structure of rock mass, nevertheless, the effect of fracture width on rock mass stability is not considered in the model. Based on the in situ investigation of discontinuity traces in sampling window, the fracture widths of sampling window is analyzed by the method of combining chisquare test and K-S test, and finally, the optimum probability distribution types were chosen. The statistic analysis results showed that the main distribution type of fracture widths of Liaoyang Shimen dinas rock slope is gamma distribution, most fracture widths are under 10mm, and type of tectonic stress affected the distribution parameters of fracture widths greatly. This result can provide theoretical basis for 3D network modeling of the fracture width.

Key words: 3D network, fracture width, stochastic mathematics, chisquare test, K-S test
