本文结合某工程船闸边坡开挖方案及实际地质资料,在考虑结构面倾角、倾向二维正态分布特性条件下,通过将块体理论与力学的、概率的分析手段结合起来,提出了一种计算某类块体成为关键块体及其稳定性满足特定要求的概率大小的方法。利用这种方法对岩体中一组结构面进行了具体分析。计算结果表明,该方法可以作为一种从概率角度评价开挖面上块体稳定性的新途径。
Based on the excavation scheme and actual geologic data of an engineering shiplock slope, this paper proposes a new method combining the block theory with the mechanics and probabilistic analysis, taking into account the two-dimensional normal distribution of structural face dip and dip. A method of calculating the probability that a certain type of block becomes a critical mass and its stability meets certain requirements. Using this method, a set of structural planes in rock mass are analyzed concretely. The calculation results show that this method can be used as a new way to evaluate the stability of block on the excavation face from the perspective of probability.
