Abstract. During the 12 May 2008 Wenchuan earthquake, a large landslide of approximately 30 million m3 occurred at Donghekou with a particle run-out distance of over 2000 m. This paper presents fascinating particle flow and segregation characteristics in the landslide process found through field investigation of changes in the soil particle size, density, and fabric along the particle movement paths. The soil particles experienced projection, long-distance flying, sliding, and rolling. Trajectory segregation, inverse grading, and particle crushing were found in the landslide event, which contributed to the heterogeneity of the soil deposits. In the initial deposition area, particles with larger diameters appeared to have flown longer. Materials from different sources mixed, forming more uniform debris. In the run-out area, the particle flow tended to cause large particles to travel further. However, particle disintegration and crushing led to more small particles along the movement paths and the observed characteristic flow distances of very large particles did not increase with the particle diameter, which is different from observations of an idealized granular mass flow.

STUDY ON RATIONALITY OF THE METHOD OF LANDSLIDE THRUST FORCE CALCULATION AND ITS IMPROVEMENT

Journal of Mountain Research (2000)

Runqiu Huang

The reliability of the value of landslide thrust force is directly relevant to its calculation method. In this paper, the applicability of transfer coefficient method is discussed and its improvement path and method are put forward as follows: landslide thrust force can be calculated through improved Swedish method and Jabu's method, the corresponding formulas are deduced. These will benefit to prevention project design and evaluation.
