| 英文摘要 | The NE-trending Yingxiu-Beichuan and Guanxian-Anxian faults in the Longmen Shan fault zone are responsible for the 12 May 2008 M(S)8.0 Wenchuan earthquake. Based on the interpretation of post-quake high-resolution remote sensing imagery and field geologic observations. the geometry and kinematics of co-seismic surface rupture as well as the seismic and geologic hazards along the Beichuan segment between Leigu Town and Qushan Town. Beichuan County. are analyzed in detail. Results indicate that surface deformation appears as an oblique thrusting with near equal vertical and right-lateral displacements ranged from 2 to 10 m, in which the largest displacement Occurred along this segment in the Yingxiu-Beichuan fault. A notable distribution feature of geologic disasters and building damages induced by this earthquake shows hanging wall effects across the surface rupture zone: the highest density of landslides, rock falls, debris flows and building damages occurred on the northwest (hanging wall) side of the fault, but few geologic disasters developed on the southeast (foot wall) side of the fault. These effects are caused directly by the asymmetric fault geometry and the stress interaction between the fault motion and free surface of the slopes. Other factors such as material heterogeneity and spatial variation in frictional properties along the fault strike may further affect the rupture and slip patterns of oblique thrust faulting with a right-lateral strike-slip component. |
