| Abstract: | Take the highway embankment in cold regions as the research object,using bran,density of which similar to natural old fine-grained snow,as the model snow,through indoor wind tunnel test,the threshold velocity for snow particles starting move and the deposition and erosion processes on different parts of an embankment were investigated.In addition,the relationship between deposition area of snow particles along an embankment and embankment profile was determined.Further more,the erosion effect of snowmelt on... |
