安徽无为市浪尖山灰岩矿边坡稳定性安全等级数据

通过分析安徽无为市浪尖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
采集安徽无为市浪尖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 the Langjianshan Limestone Mine slope in Wuwei City, Anhui Province, so as to ensure the safety and stability of slope engineering. The dataset can be applied to the following scenarios:
(1) Slope engineering design and construction: Accurately assess slope stability and provide scientific basis for engineering design and construction;
(2) Geological disaster early warning and prevention: Conduct real-time monitoring of slope stability to realize dynamic assessment and early warning, and support geological disaster prevention and control;
(3) Land resource planning and utilization: Assess the impact of slope stability on the surrounding environment to ensure the safe and rational utilization of land resources;
(4) Scientific research and teaching: Serve as an important tool in fields such as geotechnical engineering and geological engineering, and be used for research and teaching.

1. Data Source
Geotechnical physical and mechanical parameters (including soil cohesion c, internal friction angle φ of soil layer, unit weight γ of soil layer, etc.) and geometric morphological parameters (including slope height H, slope angle α, slope surface displacement L, etc.) of the Langjianshan Limestone Mine slope in Wuwei City, Anhui Province were collected.

2. Data Processing
The stability safety factor and stability level of the slope are obtained by calculating the sliding moment Mr and anti-sliding moment Mr' of the slope.
Sliding moment Mr = T × (H / sin(α));
Anti-sliding moment Mr' = c × L × (H / sin(α)) + γ × H² × cos(α) × tan(φ) / 2;
Stability safety factor Fs = Mr' / Mr;
When Fs > 1, the slope is stable, and the larger the Fs value, the more stable the slope. Conversely, there is a risk of slope failure; when Fs = 1, the slope is in a limit equilibrium state; when Fs < 1, the slope is about to fail.
