Loess side slope flaking is one of the main forms of the loess slope face destroy,it existed universally on the road of huang-yan highway。As a result of former highway classification about road-lineament is relative low,so the side slope flaking plant disease has not been able to come into the picture。Though in the building of huang-yan highway,we had take into account about higtway-lineament building,Loess side slope flaking exist vastly。So,the research of the mechanism and therapy of Loess side slope flaking is very essential。By investigating and analyzing the loess side slope flaking disease and protection present situation of the road of huang-yan highway,combineing with the natural-environment、geology-environment,meantime,referrenceing the literature-data bank,we had made a systematically and detailedly research about the mechanism and therapy of Loess side slope flaking。we obtain the following conclusions:1. According to the locale investigation of loess side slope flaking plant disease,we had made a detailed and rounded summing-up。2. Unifying the loess region natural-environment、geology-environment,we had made a analysis from the internal cause、the external factor and the human factor three aspects , researching the principium of the loess side slope flaking,mean time,generalizeing the general regularity of the loess side slope flaking。3. By building the finite elements model,we had made a simulation about the occurrence and development of the loess side slope flaking。Researched the transformation of internal displacement、stress、strain and yieldance in the loess side slope flaking。4. we had come up with idiographic shelter method in allusion to the loess side slope flaking phenomenon。
