公路岩土区划中的土分类体系与类型分布

Classification System and Type Distribution of Soil in Highway Rock and Soil Zoning

为进行中国公路岩土区划,在分析已有的土类型划分方法的基础上,提出服务于岩土区划的土分类体系;基于ArcGIS9.1编制了《中国公路土类型分布图》,据此研究了中国公路土类型的区域分布特征。这项研究可为中国公路岩土区划乃至公路灾害区划、公路自然区划等区划研究提供基础图件,并用于指导公路建设。

For studying highway rock and soil zoning in China,based on analyzing the existing soil type classification methods,the soil classification system is proposed,and the distribution map of highway soil types in China is compiled through spatial analysis by using Arc GIS 9.1.Finally,the regional distribution of soil types is studied.Carrying out the study of soil zoning for highway is of vital significance for the construction and development of highway engineering and the further zoning work such as rock and soil zoning,disaster zoning,natural zoning of highway and so on.
