Abstract

Prevention and mitigation of rainfall induced geological hazards after the Ms=8 Wenchuan earthquake on May 12th,
2008 were signifcant for rebuild of earthquake hit regions. After the Wenchuan earthquake, there were tens of thousands
of fractured slopes which were broken and loosened by the ground shaking, they were very susceptible to heavy rainfall
and change forms into potential debris flows. In order to carry out this disaster reduction and prediction effectively
in Longmenshan region, careful real-time monitoring and pre-warning of mountain hazards in both regional and sitespecifc scales is reasonable as alternatives in Wenchuan earthquake regions. For pre-warning the failure of fractured
slopes induced by rainfall, the threshold value or the critical value of the precipitation of hazards should be proposed.
However, the identifcation of critical criterion and parameters to pre-warning is the most diffcult issue in mountainous
hazards monitoring and pre-warning system especially in the elusive and massive fractured slopes widespread in
Wenchuan earthquake regions. In this study, a natural coseismic fractured landslide in the Taziping village, Hongkou
County, Dujianyan City, was selected to conduct the feld experimental test, in order to identify the threshold parameters
and critical criterion of the fractured slopes of Taziping. After the feld experimental test, the correlation of rainfall
intensity, rainfall duration and rainfall intensity was investigated. The feld experimental test was capable of identifying
the threshold factors for failure of rainfall-induced fractured slopes after the giant earthquake.
