Researches and application of key technologies for risk analysis and emergency rescue of landslide-dammed lakes

The landslide-dammed lake caused by earthquakes or heavy rains will threaten the lives and property of people in the downstream. It is necessary to timely and accurately collect and process the data with respect to the dammed lake for the risk identification and analysis. And this will also provide a scientific basis for emergency rescue, risk eradication and disaster reduction for the landslide-dammed lake. Based on the emergency rescue and disposal project of Hongshiyan landslide-dammed lake, a set of key technologies for disasters of landslide-dammed lakes are developed containing the collection and integration of emergency rescue data, the identification of risk factors and emergency command platform, and they are successfully applied to the emergency rescue and subsequent treatment of Hongshiyan landslide-dammed lake. This technical system solves the problems of quick response and scientific decision-making in the emergency rescue of landslide dams.
