中文摘要：根據(jù)對廣東某滑坡的分析，其屬于蠕滑-拉裂型滑坡亚洲5566。

The feature of typical multiple rotational loess landslides is: large scale, deep sliding face, three-five sliding face cascades, single landslide with the "plough" structural character of behind high and sheer-middle subdued-front tilt. The main formation mode of landslide is creeping-sliding-tensile fracturing. The failure modes contain extensive rotation sliding, digressive rotation sliding and compound rotation sliding.

Fracture is caused by sheet's tensile instability, Hill's totalized instability theories and Swift's diffuse instability theories which based on continuous mechanics are applied to isotropic blank; Marciniak and Kuczynski's theories are applied to orthotropic blank, which introduced thickness imperfections normal to the principal stress and strain direction as a groove pre-existing defects in the material. The stability of each part of blank at each moment is described by numerical method, and the results are shown by computer simulation, thus the fracture in sheet forming can be predicted preciously.
