| 中文摘要: |
| 伊洛瓦底江(伊江)江心岛2010年起进入退化期，岸线消退，管道穿越的河段存在险情。为维持河道稳定，消除油气管道安全隐患，采用了膜袋混凝土、透水丁坝群、刚性护岸、半刚性护岸和简易护坡等手段进行河道和岸坡的长期治理。为评价伊江管道穿越河流治理方案和成效，结合伊江河段的演化特点和历年治理工程，采用江心岛面积、冲蚀程度和管道埋深等指标综合评判不同阶段治理方案对穿越段河道和管道安全的影响。结果表明：以调节水流、加强护岸、落淤护滩为核心措施的治理方案延缓了江心岛的退化及主河道向西迁移的趋势，在汛期有效保障了管道安全，露管现象逐渐消除。伊江系统治理经验可为类似工程整治提供借鉴。 |
| 英文摘要: |
| Since 2010,the island in the heart of the Irrawaddy River(Yi River)has entered a period of degradation,with receding shorelines and dangerous conditions in the river section crossed by the pipeline.In order to maintain the river stability and eliminate the safety hazards of oil and gas pipelines,membrane bag concrete,permeable ding dam cluster,rigid bank protection,semi-rigid bank protection and simple slope protection have been used for long-term river and bank management.To evaluate the management scheme and effectiveness of the river crossing of Yi River pipeline,this paper combines the evolutionary characteristics of the Yi River section and previous years' management projects,and uses indicators such as the area of the river core island,the degree of erosion and the burial depth of the pipeline to comprehensively evaluate the impact of different stages of management schemes on the safety of the river and pipeline in the crossing section.The results show that the treatment scheme with the core measures of regulating water flow,strengthening bank protection and siltation protection has slowed down the degradation of the river core island and the trend of westward migration of the main river channel,and has effectively ensured the safety of the pipeline during the flood season.The phenomenon of exposed pipe has been gradually eliminated.The experience of Yi River system management can provide a reference for similar projects. |
