Study on the Selection of Characteristic Parameters and the Location in Slope Monitoring

Abstract eng:
The landslides bring the enormous property loss and life threat to people under the effect of natural force and human activities. Monitoring is one of the most powerful means to the space-time forecast of the sliding. Because these slope structures are not always in the same way, and the factors inducing sliding affect each other, the selection of monitoring characteristics parameters and the location of monitoring region became the key points in the slope monitoring. But there is no mature theory and analytical method at present for the two problems and more researches should be needed. The monitoring characteristic parameters and the location of sliding monitoring region are studied in the paper. At first, the deformation features of the different landslide and the structure of the slopes are analyzed and based on the results the different characteristic parameters of slope structures in different deformation stages are attained. According to the dominant deformation model, the main characteristic parameters are determined. Then, the numerical simulation technology is used in determination of monitoring location by combining a actual engineering project. The numerical model according to the monitoring object is established. The characteristic parameters are analyzed by the numerical simulation. We obtained the affecting area and the scope of the parameter variation in diverse loading stages.
