输气管线大开挖与定向钻穿越防洪调蓄生态红线的环境影响分析

长输天然气管道其穿越方式的合理选择既是管道敷设设计的难点,也是环境影响的重点问题。比选了大开挖与定向钻穿越防洪调蓄生态红线的施工工程要求和环境影响,为环评工作者科学评价输气管道穿越敏感区提供借鉴。

The reasonable crossing technique of long-distance natural gas pipelines is a difficulty for pipeline layout design and environmental impact analysis. The article compares the engineering requirements and environmental impacts from the excavation and directional drilling through the flood control and storage ecological red line,and provides reference for the environmental assessment workers to evaluate the gas pipeline crossing sensitive areas scientifically.
