Abstract Daguangbao landslide(DGB landslide) is the largest landslide triggered during Wenchuan earthquake 2008. It is also one of the most catastrophic landslides around the world during the past 100 a. DGB landslide is in the area of carbonate rock and about 5 km away from the seismogenic fault and 85 km from the epicenter. However,this landslide changed the landforms of a region about 10 km2 with a volume of 11.59×108 m3. Additionally,DGB landslide exposed a main scarp with an average height of 600 m(maximum height of 850 m),an open tension flank in the north with a length of 1.5 km and a sliding surface in the south with a length of 1.8 km. The river in front of DGB Mountain was filled up with a dam of 800 m in height. These incredible landslide features had attracted the wide concerns. Based on the previous studies and our observations in the past 7 years,the geology setting and earthquake-induced ground shaking were presented in detail in this paper. The distribution and properties of the 112 large-scale landslides triggered by Wenchuan earthquake were studied,and it was found that a bedding fault under Mt. DGB and the amplification of seismic ground motion in DGB area were the precondition of DGB landslide. Petrologic studies on the slip zone of DGB landslide microscopically were carried out and macroscopically and experimental investigation of the rock properties was performed. The results indicate that the rock mass of slip zone dilates during the earthquake. Site observation indicates that the dilatation of slip zone is resulted from the impact loading during the earthquake due to the amplification of seismic shaking. The shear strength of the materials in the slip zone was estimated. The results indicate that the reduction of shear strength due to rock fragmentation could not result in a sudden failure of DGB landslide. Recently,the ground water in Mt. DGB was investigated. The site evidence indicates that Mt. DGB has rich ground water with the well-developed vertical drainage before the earthquake. It is hypothesized that the vertical drainage is connected instantly during the earthquake,and that the ground water swarms into the dilated bedding fault which induces water hammer within this layer. A model of water hammer force in open tension crack was established,and the water hammer pressure was calculated. The results show that the maximum pressure is 20 MPa when the height of water head is assumed in a range of 70–360 m. It is concluded that water hammer pressure reduces the shear strength suddenly,and that the landslide is initiated with the high initial velocity. Finally,an improved model of DGB landslide mechanism was proposed.
