天然气长输管道汉江穿跨越方案研究

摘要

As a control projects, crossing engineering plays an important role in oil and long gas pipelines ,specifically the crossing location selection and crossing program .This paper took Shiquan Hanjiang River crossing in the pipeline project from Hanzhong to An -kang as an example.From the technical, economic and environmental aspects , the authors researched the crossing river location , pipe-line crossing river way and crossing structure program , which made the project reasonable , economic, environmental and ecological harmony.%　　穿跨越工程作为控制性工程，对石油天然气长输管道工程起着举足轻重的作用，穿跨越位置的选择和穿跨越方案的确定更是至关重要。本文以陕西省天然气管网汉中至安康输气管道石泉汉江跨越工程为例，从技术、经济、环境等方面研究了穿跨越河段选址、管道过江方案以及跨越结构形式，为该工程确定穿跨越过江方案。
