摘要:
［目的］为实现轨道交通的降本增效与低碳转型，特对绿色低碳城市轨道交通规划设计与实践进行研究。［方法］深圳地铁6号线以全寿命周期可持续发展为目标，通过综合选线优化敷设方式(高架为主)，创新应用高架线路综合减振降噪技术、预制装配式绿色建造(如U形梁、浮置板轨道)、分布式光伏发电、再生制动能量回馈、生态海绵车辆段设计、智慧化云平台及TOD(公交引导发展)模式土地集约化利用等系统性技术，探索绿色低碳规划设计与实践路径。［结果及结论］深圳地铁6号线的绿色低碳技术体系成效显著：较全地下方案节省建设成本约45%(109亿元)，减少建设期碳排放240万t；运营期能耗降低40%(年节电3 360万kW·h)，25年累计减排58万t；光伏与再生制动技术年发电节电678万kW·h；土地开发收益预期达300亿元。该案例为城市轨道交通实现“双碳”目标提供了可复制的技术集成方案，证明绿色低碳与高质量可持续发展可通过系统性创新协同实现。
Abstracts:
［Objective］ To achieve cost efficiency and lowcarbon transformation in rail transit, the planning, design, and implementation of green and lowcarbon urban rail transit systems is investigated. ［Method］ Aiming at lifecycle sustainable development, through comprehensive route selection and laying methods optimization (mainly elevated), Shenzhen Metro Line 6 innovatively applies systematic technologies such as comprehensive vibration and noise reduction technology for elevated lines, prefabricated and assembled green construction (such as Ushaped beams and floating plate tracks), distributed photovoltaic power generation, regenerative braking energy feedback, ecological sponge vehicle depot design, intelligent cloud platform and TOD (transit oriented development) model intensive land utilization, etc., to explore green and lowcarbon planning, design and practice paths. ［Result & Conclusion］ The green and lowcarbon technology system of Shenzhen Metro Line 6 has demonstrated remarkable outcomes: construction costs are reduced by approximately 45% (10.9 billion yuan) compared to a fully underground scheme, with a 2.4 millionton carbon emission reduction in constructionphase. The operational energy consumption is decreased by 40% (annual electricity savings of 33.6 million kW·h), with accumulated carbon emission reduction of 580 000 tons in 25 years. The annual power generation and energy saving by using photovoltaic and regenerative braking technologies are 6.78 million kW·h； the land development income is expected to reach 30 billion yuan（RMB）. This case provides a replicable technology integration solution for urban rail transit to achieve the carbon peak and carbon neutrality（shorten as "dual carbon"）goals, proving that the green, lowcarbon and highquality sustainable development can be collaboratively achieved through systematic innovation.
