摘要
本文系统地总结了海州露天煤矿非工作帮近40年来的62次滑坡资料，分析研究了沿弱层干面滑坡时的三维滑体空间形态。将岩体性质看作有空间变异的随机场，利用可靠性理论推导出了最危险滑体长度和三维可靠指标的计算公式，这些公式解释了沿弱层滑坡时滑体的长高比较大的原因，并可用于滑体长度及三维可靠指标的定量计算。
This paper analyses and studies the three dimensional sliding mass spatial shape by examining the62 landslide data on the no-working slope of Hanzhou Surface Coal Mine. The properties of rock massare looked upon as the random field with spatial variability. The formulae calculating critical slidingmass length and three-demensional reliability indices are obtained by means of reliability theory. Theseformuale satisfactorily exlain why the ratio of the length to the height of the sliding masses those landslides occur on soft and weak layers is larger. They may be used to quantitatively calculate sliding mass lengths and three-dimensional reliability indices.
