目前通过深部位移监测的位移曲线对不稳定边坡判别已经得到大量应用,且较为成熟,但目前很少进行在边坡开挖之前到边坡开挖之后的深部位移监测,即坡体开挖前自然稳定的位移监测特征曲线向不稳定状态发展时的位移监测曲线形态特征还不十分清晰。本文通过总结现场边坡开挖过程中深部位移监测曲线,来验证边坡稳定性计算的成果,达到通过边坡深部位移监测变形特征曲线来反映边坡开挖过程中的稳定性演化规律,是坡体稳定性评估一种可靠的方法。
At present, the displacement curve monitored by deep displacement has been widely applied to the identification of unstable slopes, and is relatively mature. However, it is rare to carry out deep displacement monitoring before slope excavation until the slope excavation, that is, slope excavation The characteristics of the displacement monitoring curve before the natural stability of the displacement monitoring characteristic curve is unstable are not yet clear. In this paper, the results of slope stability calculation are verified by summarizing the monitoring curve of deep displacement in the process of on-site slope excavation, and the stability evolution law of slope during slope excavation is reflected by monitoring the deformation curve of deep slope displacement. A reliable method for slope stability assessment.
