Abstract:

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.

Key words: shape acceleration array system, deep displacement monitoring, landslide monitoring, inclinometer, Constitutive model
