Study on Slope Stability Monitoring and Warning System about the Long Distance Transportation Line in Loess Regions

The landslide geohazard frequently occurs in the loess region in Northwestern China. Long distance transportation line project covers through varied Loess plateau geology elements. It endurs landslide infringement. Taking a key locality of the long transportation line project in loess regions as study object in this paper, the research work focuses on regional and monomer landslide forecasting warning models and the landslide monitoring and warning system based on GIS. The emphasis falls on the designing and development of the landslide geological hazard monitoring and warning system in study area. On the basis of prolific geological statistics, the basic spatial data, geohazard thematic data, project data and monitoring data of study area can be impact into the landslide geohazard monitoring and warning system with GIS. The structure and composition of forecasting and warning GIS system are analysized by combining with the study on warning models.
