On the basis of field investigation and information research in Shenmu County, according to the fundamentals of air flow pressure field theory, the specific wind erosion laws are analysed and soil coarsening causes are discussed.
得出如下结论:①土壤强烈风蚀主要发生在迎风坡、丘顶及气流发生辐合的沟谷段;②片沙主要堆积在气流发生涡动的背风坡及气流发生辐散的沟谷段谷坡;③迎风坡及丘顶土壤粗砾化是由于强烈风蚀所致,背风坡土壤沙化、粗化是沙粒堆积所致。
Based on engineering performance of foundation nearby dam culvert monitoring section, gravel soil, and anti—seepage slot of"500"reservoir, the monitoring data of dam body seepage were analyzed, then the velocity and stable seepage were calculated.
