摘要
边坡稳定安全系数受到多方面因素的影响,地下水位线的位置对边坡稳定的影响较大。通过对各种边坡模型的计算分析表明,地下水位变化对边坡稳定性的影响是有一定的规律的,地下水位在距坡脚3/10～4/10坡高范围内变化时对土坡的稳定安全系数影响不大。随着地下水位线的升高,边坡的稳定安全系数线性减小,可能发展为整体滑动破坏。
Slope stability safety factor is influenced by many factors, in which the condition of water table change affects greatly. The analysis and calculation of the stability safety factor based on diversified slope models indicate that there are certain rules of effect of water table on soil slope stability. Through calculation of the stability factor of the slope with two different software based on theory of limit equilibrium, it is shown when the water table changing between the range of 3/10-4/10 the height of the slope, it affects the stability of the slope negligibly. With the water table rising, the safety factor linearly reduces, and it is likely to induce landslide.
