- 摘要:
- 为了解我国中小型城市排水管网的整体健康状态，对长江流域某城市排水管网的缺陷检测数据进行了系统分析，重点探讨了缺陷类型、数量、等级、平均等级、缺陷密度、空间分布和区域差异特征等。结果表明，结构性缺陷以错口、腐蚀和破裂为主，占比接近80%；功能性缺陷则以障碍物、沉积和树根为主，占比约94%。缺陷等级主要为1~2级，占比84%~90%；排水管网平均缺陷等级低于2级，整体处于中等健康水平。管道缺陷密度高达100~200处/km。在空间分布上，结构性缺陷多集中于管道顶部，功能性缺陷则主要位于底部。此外，缺陷类型与地面荷载、管材及流体特性等密切相关。研究成果可为排水管网的区域化高效管理、主动维护策略制定及缺陷修复技术研发等提供科学依据。
- Abstract:
- To assess the overall health of drainage networks in small-to-medium-sized cities in China, defect detection data from the drainage system of a city in the Yangtze River basin were analyzed. The analysis focused on defect types, quantities, grades, average defect grade, defect density, spatial distribution, and regional differences. The results indicate that structural defects primarily consist of joint misalignments, corrosion, and fractures, accounting for nearly 80% of all defects. Functional defects are dominated by obstructions, sedimentation, and root intrusion, making up approximately 94%. The majority of defects are classified as grade 1 or 2, representing 84% to 90% of the total, with an average defect grade below 2, indicating a moderately healthy overall condition. The defect density is exceptionally high, reaching 100 to 200 defects per kilometer. Spatially, structural defects are concentrated near the top of the pipes, whereas functional defects are mainly found at the bottom. Furthermore, defect types are closely associated with surface loads, pipe materials, and fluid characteristics. The results provide a scientific basis for the regionalized and efficient management of drainage networks, the formulation of proactive maintenance strategies, and the development of defect remediation technologies.
