| Abstract: | Spalling hazard affects the surface stability and its appearance. Conclusions can be made by investigating the spalling hazard in loess slopes on Huanglin-Yan'an expressway in Shaanxi province, with the assistance of theoretical analysis. The development state of spalling hazard is related with the factors including layer and lithology, geographic and geomorphic conditions, geological structure, the style of slope and its angle value. This paper establishes the classification criteria of spalling hazard in loess slope after combined with topological engineering method and the appraise of spalling hazard in loess slopes. The spalling hazard development state is represented by the correlation function. The calculation method for Matter-Element correlation degree is put forward. The method has a very important role in loess area for investigation and treatment of loess apalling hazard in loess slopes. |
