油气长输管道工程施工不可避免地会扰动原始地貌，削弱土体稳定性并诱发水土流失，进而威胁管道本体安全。生态袋结构作为一种新型生态水工保护措施，兼具防治水土流失和改善生态环境的作用，已在油气管道水工保护工程中得到广泛应用。但其稳定性受堆砌形式、连接扣布置、加筋技术和施工质量等多因素影响。结合工程实例，分析不同因素对生态袋水工保护结构稳定性的影响机制，并采用极限平衡法计算和验证分析结果，以期为该技术的进一步推广应用提供借鉴。
The construction of long-distance oil and gas pipelines inevitably disturbs the original landform, weakens the stability of soil, and induces soil erosion, which in turn threatens the safety of the pipeline. The ecological bag structure is a new type of ecological hydraulic protection measure, which has the function of preventing soil erosion and improving the ecological environment. It has been widely used in the hydraulic protection project of oil and gas pipelines. However, its stability is affected by many factors, such as stacking form, connection buckle arrangement, reinforcement technology, and construction quality. In this paper, combined with engineering examples, the influence mechanism of different factors on the stability of ecological bag structure for hydraulic protection was analyzed, and the limit equilibrium method was used to calculate and verify the analysis results, so as to provide reference for the further popularization and application of this technology.
