一种岩质边坡结构面三维随机网络模拟方法
|
摘要
本文基于非接触摄影测量技术和Monte-Carlo原理提出了一种岩质边坡结构面三维随机网络模拟方法,包括野外采样、结构面分组、参数概率分布模型建立以及三维网络模拟等。以辽宁鞍千铁矿许东沟采场某岩质边坡调查点为工程背景,详细介绍了方法的实施过程并对有效性进行了验证。结果表明:本文所述岩质边坡结构面三维随机网络模拟方法能够应用于工程实践,可为边坡岩体三维强度确定、尺寸效应分析以及岩质边坡稳定性评价等提供理论依据和参考。
Based on the non-contact photograph technique and the Monte-Carlo random theory,a new three-dimensional network modeling method of discontinuities in rock slopes is proposed that includes details about surveying discontinuities of rock slopes in the field,determining the distribution of discontinuities,constructing of probability distributed discontinuities in a rock slope and 3 D network simulation. The investigation site of the rock slope in Xudonggou open pit of Anqian iron mine in Liaoning province was taken as an engineering background. The implementation process of the method was introduced in detail and the validity of this method was verified. The result shown that the three-dimensional simulation method of discontinuities in rock slope proposed in this paper was reliable. The method can provide theoretical bases and references for determining the three-dimensional strength of rocks in the slope,size effect analyses and stability analyses of rock slopes.
