宣城市狼山灰岩矿边坡稳定性安全等级数据

通过分析宣城市狼山灰岩矿边坡稳定性安全系数来判断边坡的稳定性安全等级，以保障边坡工程的安全稳定，该数据可应用于以下场景：（1）边坡工程设计与施工：精确评估边坡稳定性，为工程设计与施工提供科学依据；（2）地质灾害预警与防治：实时监测边坡稳定性，实现动态评估与预警，支持地质灾害防治；（3）土地资源规划与利用：评估边坡稳定性对周边环境的影响，确保土地资源的安全合理利用；（4）科研与教学：作为岩土工程、地质工程等领域的重要工具，用于研究与教学。1.数据来源
采集宣城市狼山灰岩矿边坡的岩土物理力学参数（如土层粘聚力c、土层内摩擦角φ、土层重量γ等）、几何形态参数（如边坡高度H、坡角α、坡面位移L等数据。
2.数据处理
通过计算边坡的滑动力矩Mr和抗滑力矩Mr' 得到稳定性安全系数，并判断边坡的稳定水平。
滑动力矩Mr= T × (H / sin(α))；
抗滑力矩Mr' = c × L × (H / sin(α)) + γ × H² × cos(α) × tan(φ) / 2；
稳定性安全系数Fs = Mr' / Mr；
当Fs>1时，边坡稳定，Fs值越大，表示越稳定，反之，则边坡存在失稳风险；Fs=1时，边坡处于极限平衡状态；当Fs<1时，边坡即将破坏。

This dataset is used to determine the slope stability safety grade by analyzing the slope stability safety factor of Langshan Limestone Mine in Xuancheng City, so as to ensure the safety and stability of slope engineering projects. The data can be applied to the following scenarios:
(1) Slope Engineering Design and Construction: Accurately evaluate slope stability to provide scientific basis for engineering design and construction;
(2) Geological Disaster Early Warning and Prevention: Conduct real-time monitoring of slope stability, realize dynamic assessment and early warning, and support geological disaster prevention and control;
(3) Land Resource Planning and Utilization: Evaluate the impact of slope stability on the surrounding environment to ensure the safe and rational utilization of land resources;
(4) Scientific Research and Teaching: As an important tool in fields such as geotechnical engineering and geological engineering, it is used for research and teaching.

1. Data Sources
Geotechnical physical and mechanical parameters of the slope in Langshan Limestone Mine, Xuancheng City were collected, including soil cohesion c, internal friction angle φ of soil layer, unit weight γ of soil layer and other related parameters; as well as geometric morphology parameters such as slope height H, slope angle α, slope surface displacement L and other related data.

2. Data Processing
The stability safety factor is calculated by obtaining the sliding moment Mr and anti-sliding moment Mr' of the slope, and the stability level of the slope is judged.
The sliding moment $M_r = T imes (H / sin(alpha))$;
The anti-sliding moment $M_r' = c imes L imes (H / sin(alpha)) + gamma imes H^2 imes cos(alpha) imes an(phi) / 2$;
The stability safety factor $F_s = M_r' / M_r$;
When $F_s > 1$, the slope is stable. The larger the $F_s$ value, the more stable the slope; conversely, the slope is at risk of instability. When $F_s = 1$, the slope is in a limit equilibrium state; when $F_s < 1$, the slope is about to fail.
