利用阵列式位移传感系统进行地质灾害深部位移动态监测与分析

为了掌握地质灾害深部位移的变形规律,使用阵列式位移传感系统（SAA）对地质灾害不稳定体进行深部位移动态监测,并同时安装了测斜仪以进行比较分析。通过建立地质本构模型和进行"降雨-变形"模型分析,优化设计了监测线和监测点位。试验结果表明：在地质灾害监测中,使用阵列式位移传感系统进行滑坡体深部位移的监测,不仅能够实时监测到滑坡体深部位移的变形情况,还能判断出滑移面具体位置。相比于测斜仪监测,阵列式位移传感系统测量准确度更高,在滑坡地质灾害监测中有更好的应用范围和前景。

Dynamic Monitoring and Analysis of Geological Disaster Deep Displacement Using SAA

In order to master the deformation law of the deep displacement of geological disasters,the shape acceleration array ( SAA) is used to monitor the deep displacement of the geological hazard unstable body. The inclinometer system is installed simultaneously at the same place for comparative analysis.By using the geological constitutive model and the analysis of"rainfall deformation model",the monitoring lines and monitoring points are designed.The experimental results show that the use of shape acceleration array system in the monitoring of geological disasters can not only monitor the deformation of deep displacement in real time,but also judge the specific slip surface position of landslide.Compared with inclinometer system,the shape acceleration array system has higher measurement accuracy, which has a better application scope and prospect in landslide geological disaster monitoring.
