摘　　要：近年来,极端天气事件频繁发生,呈现常态化趋势,汛期在役管道面临各类自然灾害风险显著增加,迫切需要提升管道的防汛抗洪能力。为提升极端天气条件下管道顺沟敷设段山洪泥石流防护能力,基于对管道泥石流灾害形成机理的分析,通过调研目前管道顺沟敷设段已有防护工程,归纳了现有管道防护工程设计中的不足,如缺乏系统性设计、设计针对性不强、工程设防标准不足以及结构性问题等。提出了加强风险评估、更新设计理念和具体防护措施等改进建议,并通过案例详细阐述了综合治理策略的应用过程。经过汛期验证,采取的防护措施有效提升了南涧村管道顺沟敷设段山洪泥石流防护效果,为管道顺沟敷设段地质灾害防治设计提供参考。Extreme weather events have become increasingly frequent in recent years,indicating a trend toward normaliza‐tion.During flood seasons,in-service pipelines face significantly heightened risks from various natural disasters,highlighting the urgent need to enhance their flood prevention and control capacity.This paper aims to improve the protection of pipelines laid longitudinally in gullies against mountain torrents and debris flow,particularly under extreme weather conditions.Based on an analysis of the formation mechanisms of debris flow disasters affecting pipelines,as well as an investigation into exist‐ing protection facilities in these pipeline sections,the deficiencies in their design are summarized.These deficiencies include a lack of systematic approaches,insufficiently targeted measures,inadequate disaster resistance standards,and structural short‐comings.Accordingly,suggestions are proposed,such as strengthening risk assessments,updating design concepts,and imple‐menting targeted protective measures.Additionally,the application process of the established comprehensive control strategies is detailed through a specific case study.These strategies were validated during a flood season,demonstrating that the imple‐mented protective measures significantly enhanced protection against mountain torrents and debris flow in a section of pipe‐line laid longitudinally in a gully in Nanjian village.The outcomes of this study provide a reference for the design of geologi‐cal disaster prevention and control in pipeline sections located longitudinally in gullies.
