几种典型地貌条件下的管线选择

不同的地形地貌会有不同的管线选择原则，而在相同的地形地形条件下，也会有不同的线路选择方案。线路选择的优劣会直接影响管道工程的施工、投资及今后的运营管理。介绍了平原地区、山岭地区、山岖河谷地段、黄土地貌等典型地区条件一的管道选线原则和敷设方案，指出在实际定线过程中，有时在同一区段会同时出现两种地貌，应综合考虑，抓住地貌地质的主要特性，选出最优方案；在选线过程中，应把管道的稳定和安全放在首位，只有满足

How to Select the Pipeline Route Under the Different Landforms'' Conditions

The principle of pipeline route selection and pipe laying plan under the conditions of several typical landforms such as plain area,mountainous area,valley area,loess area etc. are introduced. It is pointed out that in the course of pipeline route locating,when two types of landforms are in the same area,the compre-hensisve analysis on them should be made to understand the geological properties of the landforms in order to make the optimal selection. When selecting the pipeline route,the stability and safety of a pipeline must be put in the first place. Only after meeting the demands of safety, reliability and economy should the pipeline route be a optimized pipeline route.
