Paper Abstract

With the technology of GPS, we conduct precise deformation monitoring of the Laozaoping Landslide in Chongqing for a flood period. By virtue of the precipitation data close to the landslide in the monitoring period, we researched the quantitative relationship model between the landslide displacement and precipitation. In addition, we made researches on the impacts of precipitation distribution on displacement and advanced the Landslide-Causing Index (LCI). The researches show the model for displacement of Laozaoping landslide and precipitation is statistically significant; the precipitation distribution exerts more significant effect on displacement than the amount of precipitation; it is very hard to precisely estimate the displacement of landslide in terms of the precipitation and soil moisture only.
