轨道交通济阳线开通首日,市民排队"尝鲜"。图据济南轨道交通公众号 轨道交通济阳线自济南东站驶出,一路跨过黄河到达济阳区。 2025年12月30日,济南轨道交通济阳线开通,济南黄河北岸进入"轨道交通时代"。作为济南首条开通的跨 黄轨道交通线路,全长36.1公里的济阳线如何打破黄河的物理阻隔,在交通变革中重塑城市空间、激活区 域协同? 记者于泊升济南报道 跨黄轨道迎来"首秀" 市民过河"一键刷新" "以前去济南东站或者市区常选择开车,现在坐济阳线一路直达,2元票价,还不用操心停车问题。"2025年 12月30日上午,家住起步区的市民李娟(化名)成为济阳线的首批乘客,列车穿越黄河时,她用手机记录下这 一时刻。 作为济南首条开通的跨黄轨道交通线路,济阳线的投用绝非简单的交通线路延伸,而是对黄河北岸居民出 行模式、生活半径的一次重塑。 对跨河通勤族而言,济阳线带来的不仅是"时空压缩"。在起步区某智能制造企业工作的张明明(化名),家 住历城区,以前自驾通勤早晚高峰耗时近1小时,每月油费、停车费支出超过1000元。"现在从家步行10分 钟到站点,30分钟就能到公司楼下,2元的单一票价,每月通勤成本100元左右。" 济南轨道 ...

Core Viewpoint - The launch of the Jinan Tramway, specifically the Jiyang Line, marks a significant step towards enhancing transportation connectivity between the main urban area and the Jiyang District, initiating the "Yellow River Era" in Jinan [1][3] Group 1: Project Overview - The Jiyang Line is the first urban rail project to cross the Yellow River and features a total length of approximately 35.51 kilometers, connecting Jinan East Station to Jiyang District with 16 stations along the route [3][4] - The expected completion date for the Jiyang Line is by the end of 2025, which will reduce travel time from the main urban area to Jiyang District to 40 minutes [3][6] Group 2: Additional Infrastructure Developments - The Jinan Metro Line 7, another significant project, spans about 30 kilometers and includes 23 stations, with construction progressing well as of June [4][6] - The anticipated completion date for Metro Line 7 is by the end of 2027, which will enhance connectivity with existing metro lines [6] Group 3: Strategic Importance - The construction of cross-Yellow River rail transit is aligned with Jinan's urban development strategy, promoting coordinated growth between the main urban area and northern regions [7][8] - The project aims to facilitate the movement of talent, capital, and technology to the northern areas, thereby driving industrial upgrades and urban development [8][11] Group 4: Broader Implications - The cross-Yellow River rail transit will address traffic congestion issues in Jinan by providing an efficient alternative to private car usage, thus improving overall urban mobility [11] - The project is expected to attract population and industry to the northern regions, fostering a multi-center urban development model [11]

Core Insights - The Jinan Metro Line 7's construction has made significant progress with the successful launch of the shield machine "Chunlei" for a 597-meter underground excavation, marking a fast-tracked phase for the project [1] Group 1: Challenges Faced - The excavation process is characterized by high difficulty, including sharp bends with a minimum radius of 360 meters and steep slopes of 25‰, requiring precise control of the machine's posture [3] - The project must navigate through complex geological conditions, including various soil types such as gravel, cemented gravel, silty clay, and different degrees of weathered rock, necessitating dynamic adjustments to excavation parameters [3] Group 2: Safety and Technology Measures - To ensure the safe progress of "Chunlei," the project team employs a combination of advanced techniques, including synchronized grouting and secondary grouting to fill voids and minimize ground disturbance [5] - A smart excavation strategy is implemented, optimizing core parameters like pressure and speed based on real-time geological data and monitoring [5] - The project utilizes a shield intelligent management system for precise axis control, settlement prediction, and construction visualization, enhancing risk anticipation and operational efficiency [5] Group 3: Future Outlook - The Jinan Metro Group's management team for Line 7 aims to continue leveraging technology and craftsmanship to advance construction, contributing to a more comprehensive urban transit network and enhancing city mobility [5]
