Application and analysis of gps in loess slope monitoring

摘要

The main factors which affect the stability of loess slope include earthquake, rainfall and human activities etc. For loess slope, in order to hold its health level in time and obviate the collapse disastrous sequel, all aspects monitoring, deformation analysis and forecast are needed. Based on discussions of the theories and methods of loess slope monitoring with GPS technique, this paper introduce an application project of loess slope monitoring in a mountain district of Gansu province. The deformation size and orientation of a loess slope are analyzed with the monitoring results. And bring forward the deformation development prediction model of the loess slope. Further more, some suggestions to the disaster prevention of the loess slope maintenance and management also put forward. The monitoring method, data analysis process and prediction model can be referenced and applied in related loess slope motoring.
