摘要

以西南某石灰石矿高陡边坡为研究对象，根据矿山边坡现状、边坡岩体结构和结构面发育特征因素对“现状边坡”和“终了边坡”进行地质分区，通过岩石室内物理力学试验获得坡体岩石物理力学参数，采用GSI法计算边坡岩体内摩擦角、粘聚力、变形模量和泊松比等参数，评估边坡地质强度特性，采用Morgenstern-Price极限平衡法分三种荷载工况分别计算“现状边坡”和“终了边坡”各分区稳定性系数。经分析，该石灰石矿各地质分区“现状边坡”和“终了边坡”稳定性好，采场边坡参数设计合理，可为矿山扩产安全设施设计和安全生产提供参考。

Abstract:

The high-steep slope of a limestone production quarry was used as the research object of stability analysis in southwestern China. Firstly, the engineering geological areas of present slope and end slope is divided, based on the slope engineering geological survey, the structure of slope, and the characteristics of the structural plane. Then, the limit equilibrium method of Morgenstern-Price is used to calculate and analyze the stability of the present and end slope, through out the indoor rock mechanics test to obtained the slope rock quality and the GSI index. The research results show that the present slope and end slope are all stable, and the design parameters of slope is reasonable. At the same time, it also can provides a scientific basis for the safety design and produce in quarry.

Key words: high-steep slope GSI limit equilibrium method work safety
