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.

2典型多级旋转型黄土滑坡特征表现为：规模大、滑带深、3-5级滑面分层叠置、单个滑面成后缘高陡-中部平缓-前缘微翘的"犁式"结构特征；其变形破坏方式表现为：蠕滑-滑移-拉裂-块体滑动-旋转-逐级扩展，其扩展方式主要包括：扩展式旋转滑动、渐灭式旋转滑动和复合式旋转滑动。

We get the vary rules of mechanics character, study the dilatability and fractal characters of shear surface, analyzed the distortion manner of different kinds mixture, we build the forecast model though test results, while the results are generally same by different test ,so we can use the model to preestimate the mechanics index of mixture quickly.
