Abstract The concept，classification method and structure type of early slope structure are reviewed and discussed. In order to improve and to unify the structural classification system of slopes，this paper further explains the concept of slope structure. Based on the influencing factors such as formation lithology，development degree of weak structural planes and their combinations with the slope surface，rock mass integrity，and deformation and failure characteristics，a unified classification system of slopes based on slope stability evaluation is proposed，including 5 categories of massive structure，quasi massive structure，non block structure，cataclastic structure and deformation structure，and 21 sub categories. The classification method highlights the control effect of weak structural planes and their combinations with the slope surface on the slope stability，and divides the traditional layered structure into two different types of quasi massive structure and non massive structure according to the slope stability attribute. The soil slope is incorporated and the type of deformation structure is added in the classification system. The classification basis is reasonable，easy to understand and practical. It has important guiding significance for slope geological survey and slope stability zoning evaluation，instability failure mode identification and stability analysis methods，as well as the selection of excavation and treatment design schemes.

Key words： slope engineering slope structure unified classification system weak discontinuity structural type stability evaluation
