摘要

Overview the landslide monitoring and early-warning researches achievements from three aspects as the rainfall thresholds, monitoring techniques, and regional monitoring and early-warning system. Firstly, it summarized the landslide rainfall thresholds of 28 countries or regions in the world including their study or statistic methods. Day rainfall model, antecedent rainfall model and soil moisture content model almost cover all rainfall thresholds calculation methods. On the other hand, due to the complicated water infiltrating and triggering types, different mechanism landslides “need” different thresholds. Study of coupling rainfall to water seepage to soil strength is the trends in the future.
