Style of spalling hazard in loess slope and its develop characteristic

YE Wan-jun1,YANG Geng-she2,GUO Xi-shan3 (1.College of Geology & Environment,Xi′an University of Science and Technology,Xi′an 710054,China;2.College of Architecture and Civil Engineering,Xi′an University of Science and Technology,Xi′an 710054,China;3.Editorial Board of Journal,Xi′an University of Science and Technology,Xi′an 710054,China)  
Spalling hazard of loess slope surface is serious in loess area,the basic character is summarized in general,and the named method is put up based on spalling hazard′ develop character,scale and the section shape parameter.They are named sheet-shape spalling,layer-shape spalling,chunkshape spalling,fish scale-shape spalling and mixed-shape spalling if its shape is considered.They are named surface rust spalling,middle layer spalling and thickness layer spalling if spalling thickness is considered.They are named gravity-induced spalling,scour-induced spalling,frost and thaw-induced spalling,disturbance-induced spalling,stress concentration-induced spalling,tectonic-induced spalling,weathering-induced surface spalling and biological-induced spalling if the formation reason is considered.At last,the develop character of surface spalling hazard in loess slope is discussed based on loess lithologic-stratigraphic conditions,geographic and geomorphic conditions,geological structure conditions,slope style and slope angle.
