摘要
为分析无桩加固边坡的稳定性,以鞍千矿业许东沟采场为工程背景,采用现场调查、理论分析和数值模拟等手段,主要研究无任何加固措施下,边坡中2个重要参数指标黏聚力和内摩擦角对边坡稳定安全性的影响,并分析了岩体含有节理时边坡的稳定性,研究不同节理的长度、角度和埋深等对边坡稳定性的影响。
For the analysis of the stability of the slope with no pile to reinforced, takes the Xudong ditch stope of Xueqian coal industry as the engineering background, the field investigation, theoretical analysis and numerical simulation methods were used to research the two important parameters in the cohesive force and internal friction angle of impact on the safety of slope stability without any reinforcement measures, and the influence of different joint length, angle, and buried depth of different joint are studied as well.
