摘　　要：滑坡的监测主要是基于滑坡体的空间几何形态的变化特征,由于滑坡的变形不均匀、运动周期长、应变量小等特征,导致滑坡的监测难度大、监测周期长。为此,基于姿态传感器的小体积、高速数据传输、低功耗、稳定启动时间、全角度无盲区等监测特征,本文选取姿态传感器为滑坡形变监测仪器,姿态传感器通过位移和角度的转换得到滑坡体姿态变化值,通过白什乡典型滑坡的全站仪监测和姿态传感器监测结果对比可知,姿态传感器能更准确及时的反应了滑坡体内部的变形结果,为有效地监测滑坡提供了一定的参考价值。Landslide monitoring is mainly based geometry of landslides, due to the characteristics on the variation cbiaracteristics of spatial of uneven deformation, long motion period, small strain, all which resulting in the difficult to monitor, long monitoring period. Therefore, due to the characteristics of attitude transducer Such as the small volume, high- speed data transmission, low power dissipation, stable starting time, no blind area, so the attitude sensor selected for landslide monitoring, the attitude attitude change value of land- slide got through the conversion of change value of displacement and angle, according to the Contrast value of total station monitoring and attitude sensor monitoring results of the typical landslide of Bai Shi Xiang, attitude sensor can be more accurate and timely response to the internal deformation results of landslide, all which can provide the value reference for effectively landslide monitoring.
