摘　　要：鉴于坡度因素在山区管道设计中的重要性,且目前没有一个特定的坡度指标能够综合反映区域内坡度分布特征及其与山区管道建设中诸多重要工程量之间的关系。利用MAPGIS技术生成管道途经区的坡度分布图,以此确定各个获得坡度段在区域内的分布情况,并使用分形和变换分形的方法对途经区坡度分布特征进行研究,获得坡度分布的分形和累计分形特征,并计算得到各个坡度段的分维值。结合相应区域内地质灾害的发育情况,管道线路施工图设计的热煨弯管用量及水工保护用量,探讨分维值与它们的关系,以期为山区管道设计提供有效的设计依据和技术方法。Slope factor plays an important role in the design of mountain pipeline,and no one particular slope index can comprehensively reflect the relation between the fractal feature of slopes in the region and many important project quantities in the construction of mountain pipeline.This paper confirms the distribution general of slope in pipeline route with MAPGIS technology to determine the distribution general of different slopes in the region,and carries out a study on the fractal feature of slopes in the regions that pipeline will cross over with the fractal method and the variable dimension fractal method,so that the fractal feature and accumulated feature of slope distribution can be discovered to get the fractal dimension value of different slope sections by calculation.Combined with the development tendency of geological hazards in the region,the quantity of hot bending pipe and that of hydrotechnological protection designed in pipeline installation drawing,the paper discusses the relation between the fractal dimension value and said situations,and the results can provide effective design basis and technical methods to the design of mountain pipeline.
