摘要为了探讨滑坡深部位移监测新技术及预警预报方法，介绍阵列式位移计SAA新型监测技术和常规监测方法应用于高原山区公路滑坡的深部位移监测过程，提出监测孔动能计算方法，并对滑坡从变形启动至整体失稳破坏过程中的位移速率、加速度及动能和动能变化率的变化规律进行系统地分析研究，提出基于动能和动能变化率的临滑预警方法。结果表明：阵列式位移计SAA具有量程大、稳定性高、易于实现远程监控等优越性；利用动能和动能变化率曲线的变化特征可以较好地识别滑坡的演化规律及各个阶段，并能够确定滑坡变形过程的时间阙值；通过动能和动能变化率曲线得到的滑坡预警时间和演化阶段与加速度曲线得到的结果较一致，表明所建立的预警预报方法的可行性和有效性，可望真正地实现滑坡的自动预警。

Abstract：In order to present an investigation into a novel technique for monitoring deep displacement and early-prediction method of landslide，the processes of the novel technology of SAA(shape acceleration array) and conventional monitoring method used to collect deep displacement of a certain landslide located in plateau mountain area were introduced. A method for calculating kinetic energy of monitoring bore was proposed. The change laws of deformation rate，acceleration as well as kinetic energy and its rate from beginning deformation to global sliding failure were analyzed and studied systematically. The early-warning method for critical landslide sliding based on kinetic energy and its rate was proposed. The results demonstrate that shape acceleration array offers a number of advantages including wide range，high stability，easy to implement remote monitoring and so on. The relationship characteristic curves of kinetic energy and its rate can be used to distinguish different stages of landslide and to predict limit time in the deformation process of landslide. The landslide warning time and evolution stages obtained from the curves of acceleration，kinetic energy and its rate are in good agreement，which indicates the feasibility and effectiveness of the proposed warning and forecasting method. According to the research，automatic early-warning of critical landslide sliding is expected to achieve.
