Research on the Classification of Slope Stability State Based on the Method of Vectorization Attribute Circle

This study proposed a multirange attribute object classification method based on a vectorization attribute circle to solve the classification problem of multiple slope stability. There are many factors affecting slope stability, and these factors are difficult to assign a value representation; however, they can usually be easily expressed as a range of attribute fields to adapt to this situation and propose a method based on an attribute circle. First, this paper discusses the basic properties of an attribute circle, and subsequently discusses the method, derivation process, and properties of an attribute circle. Finally, the section of the Hai Bamboo Highway on the 318 national road line in Ganzi Prefecture, Sichuan province, China, is selected as an engineering case and this study uses this method to classify 16 slopes according to four attributes. By continuously raising the threshold until all objects are classified, the classification results are the same as the actual stability in the slope sample instance. This method provides a new idea for the study of slope stability state classification.
