坡度由土壤、岩石、沙子和其他混合材料(如工业废弃物等)组成，用于填筑斜坡的路堤。边坡的物理力学性能对稳定性有很大的影响，如抗剪强度(内摩擦角、内聚力c)和体积密度(包括自然容重和饱和体积密度等)。坡度的工作条件。工作条件主要是指边坡的外部荷载，包括顶部的荷载，如车辆荷载和在公路路堤顶部的人，坝后的水压。边坡的水流动和边坡的水位变化是影响边坡稳定性的重要因素。除了对边坡的影响外，对边坡的物理力学指标也有影响。
强化的斜率边坡加固是采取人工措施，将滑移的力转移到边坡的另一个稳定部分，使整个边坡达到一个新的平衡状态。研究边坡稳定性的目的是预测边坡失稳的时间、规模和危害。要采取寻找濒危地区和调查潜在失效等预防措施，必须做好地质灾害的减灾工作，使边坡的设计达到安全、可靠、经济稳定的目的。总之，分析了外部因素对研究的改进。
The slope is formed by soil, rock, sand and other materials mixed (such as industrial waste, etc.) for fulfilling the embankment for the creation of slope. The physical and mechanical properties of the slope have a great impact on the stability, such as shear strength (internal friction angle, cohesion c) and bulk density (including natural bulk density and saturated bulk density, etc.).
Working conditions of slope. The working conditions mainly refer to the external load of the slope, including the load on the top such as a load of vehicles and people acting on the top of the highway embankment, the water pressure behind the dam. The water flow behind the slope and the change of water level in slopes are important factors affecting the stability of slopes. Besides their effects on the slope, they have an influence on the physical and mechanical indexes of the slope.
Reinforcement of Slope. The slope reinforcement is to take artificial measures to transfer the force of sliding to another stability part of the slope to make the whole slope to achieve a new equilibrium state。The purposes of studying slope stability are defined to be predicting the failure time, the scale and hazard of slope instability. To take preventive measures such as finding endangered areas and investigation of potential failure, reduction in the geological disasters must be done and making the design of the slope to achieve the purposes of safe, reliable and economic stability. Afterall, the external factors are analyzed for the betterment of the study.
