西南地区油气管道水毁与地灾治理成果调研及建议

Research on Achievements and Suggestions for Water Damage and Geohazard Control of Oil and Gas Pipelines in Southwest China

摘要: 管道工程的水毁及地质灾害是威胁管道安全稳定运行的重要因素。本文以忠武线、川气东送管道的水毁及地质灾害治理历史成果现场调研，系统分析、总结了鄂西山区段管道工程面临的水毁、滑坡、岩溶塌陷等主要地质灾害治理经验。研究发现，该区域地质构造复杂、降水集中，导致灾害频发，现有治理措施在材料选择、施工质量、监测体系等方面存在优化空间。基于此，提出了细化前期勘察、强化施工监管、建立动态监测系统等优化建议，为同类山区管道工程的安全运营提供参考。

Abstract: Pipeline engineering, as a critical energy transportation infrastructure, plays a vital role in ensuring the stable and secure supply of energy. Hydraulic protection and soil and water conservation are essential components of pipeline projects, effectively mitigating geological hazards that may damage pipelines. Based on field survey data from the Shuidong-Wuhan (Zhongwu) Line and the Sichuan-East Gas Transmission Pipeline, this paper systematically analyzes the primary geological hazards—such as water erosion, landslides, and karst collapses—faced by pipeline projects in the mountainous regions of western Hubei. It summarizes the remediation measures implemented at various hazard sites and evaluates their effectiveness. The study reveals that the complex geological structure and concentrated precipitation in this region contribute to frequent disasters, while existing remediation measures exhibit room for improvement in material selection, construction quality, and monitoring systems. Accordingly, optimization recommendations are proposed, including refined preliminary surveys, enhanced construction supervision, and the establishment of dynamic monitoring systems, to provide a reference for the safe operation of similar pipeline projects in mountainous areas.
