摘要
油气管道受到地质灾害损伤时可能会发生油气泄漏,油气散布在大气、土壤、水体等环境空间可导致着火、爆炸以及环境污染,对社会公共安全影响较大。在油气管道设计、工程建设以及运行阶段,均对管道途径地区地质状况提出了较高要求。现结合目前国内外膨胀土研究现状,梳理了历年油气管道受到膨胀土损伤案例,对膨胀土进行了野外特征以及判别指标等方面的简要分析,有针对性地提出油气管道区域膨胀土灾害防治方案措施,为膨胀土的有效管控提供了借鉴经验。
When oil and gas pipelines are damaged by geological disasters,oil and gas leakage may occur.The spread of oil and gas in the atmospheric,soil,and water environments can lead to fires,explosions,and environmental pollution,which has a significant impact on public safety.During the design,construction,and operation stages of oil and gas pipelines,high requirements are placed on the geological conditions along the pipeline route.This paper,in combination with the current research status of expansive soil at home and abroad,sorts out the cases of oil and gas pipelines being damaged by expansive soil over the years,briefly analyzes the field characteristics and indicators of expansive soil,and proposes targeted prevention and control measures for expansive soil disasters in oil and gas pipeline areas,providing reference for the effective management and control of expansive soil.
