摘要

国内、外针对高堆土体边坡稳定性监测的传统方法众多,传统方法仅当坡体发生变形时才能被监测仪器捕捉到有效数据,属于事后监测方法。自然电位法通过地表采集数据研究坡体内部结构变化,避免传统监测方法仅观测地表变形的局限性,能由表及里预警坡体稳定性情况。因此,该研究是在地表未出现明显变形的情况下监测坡体内部稳定性的技术方法,可为类似工程提供借鉴和参考。
        There are many traditional methods for monitoring the stability of high soil slopes at home&abroad.The traditional method can capture effective data only by the monitoring instrument when the slope is deformed,which belongs to the post-monitoring method.The natural potential method collects data from the surface to study the internal structural changes of the slope,avoiding the limitations of the traditional monitoring method to observe only the deformation of the surface,and can predict the stability of the slope by the surface &the inside.Therefore,the research is a technical method to monitor the internal stability of the slope without obvious deformation on the surface,which can provide reference for similar projects.
