呼包鄂管道鄂尔多斯段水毁灾害特征及防护工程优化

Flooding damage characteristics and optimization of the protection engineering for the Ordos section of Hohhot-Baotou-Ordos oil pipeline

长距离输油管道穿越鄂尔多斯丘陵地区,管道水毁地质灾害有独特的发育类型和危害特征。论文结合呼包鄂管道沿线地质灾害调查结果,总结了该区管道水毁灾害的发育特征,半定量分析了水流在各类水毁中对防护工程的冲刷破坏作用。根据已有防护工程的变形破坏模式,对鄂尔多斯地区管道水毁灾害的防护措施提出了优化建议,同时提出采用土工格栅护坡对管道过崾岘进行防护。为长输油气管道穿越鄂尔多斯地区的建设和保护提供参考。

The flooding damage of long-distance oil pipeline features unique development types and risk characteristics when pipelines cross hilly region in Ordos. Combined with the geological disaster investigation results along Hohhot-Baotou-Ordos oil pipeline, the paper summarized the developing features of the pipeline in this area, and analyzed the erosion and destruction effect of water flow on the protection engineering in different types of flooding damage semi-quantitatively. According to the deformation and failure modes of the existing protection engineering, some optimization suggestions on flooding damage protecting in Ordos are put forward, and geotechnical grille is proposed for pipeline protection aiming at the flooding damage in yaoxian area. It provides some reference for the construction and protection for long-distance oil and gas pipeline in Ordos.
