近年来，多地出台桥下空间管理办法，推动一批改造项目落地。昔日被忽视的桥下区域，经过更新蝶 变，成为兼具审美、人文、生态价值的美好空间。 改造桥下空间本质上是城市发展至新阶段的必然选择。当城市告别规模扩张的粗放模式，存量挖潜与内 涵式提升已成为重要课题。"十五五"规划建议明确提出"坚持城市内涵式发展，大力实施城市更新"， 而"一桥一策"主导的微改造、精细化提升，以切口小、投入少、见效快的独特优势盘活桥下空间，是对 城市精细化治理要求的呼应，是将"城市剩余空间"转化为"民生服务空间"的有益尝试。 不同于大拆大建的城市改造，通过小幅度改造与精细化设计来盘活桥下空间，不仅能破解停车难、公共 活动场地不足等民生痛点，能以低成本完成环境整治，嵌入多元社区功能，实现"一举多得"的治理效 能。 不过，要注意的是，盘活桥下空间绝非简单地功能堆砌，而需统筹安全、效益、成本与可持续运营的多 重平衡。安全是不可逾越的红线，桥梁结构稳固、地下管线安全、消防通道畅通等硬性要求必须置于首 位。在此基础上，兼顾功能性与环保性，才能实现安全、实用、经济的有机统一。 以创新设计让桥下"别有洞天"，差异化是"一桥一策"的生命力所在。避免"千桥一面 ...

党的二十届四中全会通过的"十五五"规划建议提出，要将"构建现代化基础设施体系"作为新时期建设现 代化产业体系、巩固壮大实体经济根基的重要任务。中央城市工作会议也提出要推进城市基础设施生命 线安全工程建设，建设安全可靠的韧性城市。城市基础设施生命线是支撑超大省份安全运行和现代化建 设的"硬底座"，关系人民群众生命财产安全，关系经济社会发展全局。江苏省委省政府始终高度重视人 民生命财产安全，把城市基础设施生命线体系建设摆在推进中国式现代化江苏新实践的重要位置，积极 探索以系统思维推进城市基础设施生命线现代化的新路径。11月17日召开的省委城市工作会议中，再次 明确要求推进城市基础设施生命线安全工程建设。 聚焦重点领域，夯实城市基础设施生命线安全底座 近年来，江苏坚持以高质量发展为牵引，把城市基础设施生命线作为提升城市安全韧性和综合承载力的 重要抓手。一方面，全省于2020年启动实施《城市建设安全专项整治三年行动实施方案》，将燃气、供 水、排水、热力、电力、通信、道路桥梁、地下空间等城市基础设施生命线纳入统一规划、统一监管， 推动基础设施布局从分散建设向系统集成转变，实现重点设施"可视、可测、可控"；另一方面，推动 ...

Group 1: Infrastructure Challenges - Traditional infrastructure is facing systemic shortcomings in risk resilience and emergency response efficiency due to outdated design standards and insufficient disaster resistance [1] - Current infrastructure design standards are primarily based on historical disaster data, which are inadequate for the increasing frequency of extreme weather events [1] - Monitoring methods are lagging, with low coverage of intelligent monitoring systems, making it difficult to detect structural damage in aging infrastructure [1] Group 2: Advancements in Urban Infrastructure - The acceleration of new urban infrastructure construction, particularly through the application of artificial intelligence, is reshaping urban disaster prevention systems [2] - The integration of digital construction, smart facilities, and information platforms significantly enhances data collection, analysis, and forecasting capabilities for urban infrastructure [2] - Technologies like digital twins are enabling simulation-based urban governance, allowing managers to optimize emergency response plans in virtual environments [2] Group 3: Disaster Management in Zhejiang - Zhejiang faces significant risks from typhoons and secondary disasters, necessitating advanced disaster management strategies [3] - The province has developed the first national resilience disaster prevention model, integrating comprehensive risk assessment and decision support systems [3] - This model can provide real-time forecasts of various risks and assist in decision-making for population relocation and resource allocation [3] Group 4: Resilience of the Power Grid - The extensive power grid system in Zhejiang is vulnerable to natural disasters, making it crucial to enhance its disaster resilience [4] - The State Grid Zhejiang Electric Power Company has established a comprehensive disaster resilience model that incorporates advanced technologies for risk forecasting and assessment [4] - This model enables dynamic risk predictions for power grid equipment during disasters and supports optimal decision-making across various stages of disaster management [4]
