- 摘要:
深根植物与油气管道同处复杂因素聚集的土壤环境中,必然相互影响。阐述了深根植物与油气管道之间的关系,列举了深根植物对油气管道的主要损伤形式,具体表现为深根植物根系对防腐层的损伤和对油气管道挤压、穿入、交叉包裹，以及深根植物根系分泌物对油气管道的腐蚀。介绍了目前较常见的深根植物根系破坏行为研究方法,包括静态观察、动态观察的现场实测法，压痕、顶破和耐根穿刺等模拟实验法以及数值仿真。提出了控制油气管道与深根植物的安全距离、增加油气管道保护措施的安全风险管控策略。针对今后油气管道附近深根植物的种植和处理方式,需结合油气管道所处环境、深根植物特点和生长特征,制定具有针对性的油气管道周边深根植物管理办法。
Deep-rooted plants and oil and gas pipelines coexist in the complex soil environments and inevitably affect each other. This paper elaborates on the relationship between deep-rooted plants and oil and gas pipelines, listing the main forms of damage caused by deep-rooted plants to oil and gas pipelines, specifically manifested as damage by roots of deep-rooted plants to the corrosion protection coating; root-induced extrusion, penetration, and cross-wrapping of oil and gas pipelines; as well as corrosion of oil and gas pipelines caused by root exudates. Commonly used research methods for studying deep-rooted plant root damage behavior are introduced, mainly including field measurement methods using static and dynamic observation; simulation tests such as indentation, puncture resistance, and root penetration resistance; and numerical simulations. Safety risk management strategies are proposed, namely, controlling the safety distance between oil and gas pipelines and deep-rooted plants, and enhancing protective measures for oil and gas pipelines. For the planting and management of deep-rooted plants near oil and gas pipelines in the future, it is necessary to consider the environmental conditions of the pipelines, the characteristics and growth traits of deep-rooted plants, and to formulate more targeted management measures for deep-rooted plants around oil and gas pipelines.
