Abstract: Sliding force greater than sliding resistance is sufficient and necessary condition of the landslide，based on this warning principle，a landslide remote real-time monitoring and prediction system is developed，and it has important meaning in forecasting and warning geological dirsasters of landslide。Based on the landslide dynamic simulation and indoor physical model experiment，the landslide warning model is preliminarily determined。And the system are applied and researched in Pingzhuang open coal mine，west-east gas transmitting pipeline project（Yan'an section），NaFen open iron mine and ShuoZhou open-underground coal mine，which has proved sufficiently the landslide warning model.Results show that the field warning model of landslide sliding force monitoring curves is consistent with the inferred model of indoor physical model experiment.Thus，this kind of warning model can be used to continue to analyze and judge the stability in the other slip mass，and make accurate warning and forecasting ahead of landslide.

Key words: Slope, Sliding force, Monitoring curves, Warning model
