| 摘 要： | 在汶川8.0级大地震后,通过对北川和映秀2个极震区地表破裂的初步调查发现:北川、映秀地震形变带总体上为NE-SW向展布;地震破裂带以逆冲为主,兼小量走滑位移;北川地表形变带挤压缩短量为3～4m,映秀地表破裂左旋走滑位移为0.4～0.5m

| Abstract: | After Wenchuan Earthquake(M8.0),surface fractures in Beichuan and Yingxiu were investigated.It was found that the earthquake deformation zone strikes in NE-SW.Earthquake fracture is characterized by thrust faulting with small amount of strike-slip movement.The compressional shortening is 3～4m in Beichuan and the left-lateral strike-slip displacement is 0.4～0.5m in Yingxiu |

| Keywords: | Wenchuan Earthquake surface fracture displacement of fault |
