| 摘要 | A deterministic formula for potential instable slope was derived from the limit equilibrium equation in the condition of the safety factor Fs=1 and the identified method for this kind of slope was then proposed here following the deriving process. Based on the hydrological process simulation, the variation rule of the saturated index w has been analyzed with different rainfall data inputs, and with this variation rule, the potential instable slopes were further analyzed, and the assessing method of potential instable slopes was established here. Taking the Wenchuan seismic disastrous area within Sichuan Province as the study zone, the potential unstable slopes has been identified by using the identified formula. The results show that the area of identified potential unstable slopes in this region is about 4554.94 km2accounting for 14.32% of the total area of the study zone. The further analysis of the stability of these identified potential unstable slopes under the action of the rainfall with different designed frequencies has been assessed, and the slope distribution with the possibility that the landslides may occur has been identified. This assessing result can provide the prevention basis for the landslides in the study zone and decrease the life and property loss caused by the landslides. © 2016, The Editorial Board of Journal of Basic Science and Engineering.
