华北东部高速公路边坡立地类型划分
Site Classification of Highway Slopes in the East of North China
摘要
Abstract
Based on the concept of micro-site coditions,the site types of highway slope were divided,in order to improve the pertinence of slope vegetation measures,to select better method for green engineering,to reduce project costs, and to improve the survival rate and preservation of slope vegetation. [Method]Slopes of Beijing-Chengde highway ( Shayugou to the city boundary) ,Langfang-Zhuozhou highway and Beijing-Shijiazhuang two-channel highway ( Dayuancun to the city boundary) in the east of north China were studied. both field surveys on highway slopes and laboratory tests were combined to investigate all the site factors. Then the data of standardized site factors were analyzed by the analysis of variance,multivariate statistical principles of factor analysis and hierarchical cluster analysis.[Result]Six site groups of highway slopes were determined: plain soil embankment slope,plain soil cutting slope,hilly soil embankment slope,hilly soil cutting slope,plain rock cutting slope,and hilly rock cutting slope. The 6 site groups of highway slopes were divided into 24 site types. [Conclusion]Finally,a site type system of highway slopes in the east of Northern China was obtained by combining the forest site classification in China and the site types of highway slopes in the east of north China,which is aimed at improving the scientific basis and rationality of slope revegetation.关键词
