The Application of ULRR-Rainfall Coupled in Forecast Prediction on Debris Landslide

Abstract:

According to the systematic analysis of the composition and destabilized mechanism of debris landslides, this paper have hydro-geological conditions of the landslide and rainfall combined, research the changes of Unload-load response ratio (ULRR), which is considered as the displacement dynamic parameter of debris landslide in the water environment of different roles and conditions. To further explore the stability and its instability law in different stages of the landslide, establish the ULRR-rainfall coupled warning model in order to improve the accuracy of landslide prediction greatly. Meanwhile, based on the example of Xintan, use the ULRR-rainfall coupled warning model to evaluate and predict its stability. The Evaluation and prediction results match the evolution of slope stability. All results above prove that the ULRR- rainfall coupled is a very effective and reliable new method in the forecast prediction of the debris 1andslide．
