lang=EN-US>Donghekou landslide, a typical rapid and long run-out landslide triggered by Wenchuan earthquake, is located in oft-com:office:smarttags" />Qingchuan County. By using the advanced DPRI ring shear apparatus, a series of ring shear tests have been carried out to study the vibration liquefaction process of Donghekou landslide under the loading of real seismic waves. The results show that with the vibration liquefaction, the shear strength could be decreased and a large displacement could be generated, which supplied a necessary condition for the generation of rapid and long run-out landslide.oft-com:office:office" />
