齐鲁晚报·齐鲁壹点 记者 王皇 喻雯 季明智 9月25日,济南五龙潭月牙泉,泉水有力蹦出蘑菇石,倾泻而下,"月牙飞瀑"盛景引来无数游人留影。月牙泉在济南72名泉中喷涌水位最高,通常趵突泉水位达到29 米时才能复涌,是所有泉群全部喷涌的"信号泉"。在它南侧约1.9公里,最繁忙的经十路上,地铁4号线空载试运行的列车穿城而过,做着通车前的最后冲刺。 这是世界上首条邻近泉水敏感区的地铁线路,也是济南首条在城市最繁忙的经十路下东西川流的地铁线路。一边是南依泰山、北靠黄河的东西狭长城市亟须 解开的拥堵之困,另一边是潜流地下涌动城市生机的泉脉之珍,为泉水让路、与泉水共生,成为4号线地铁建设的主动选择。 济南地铁4号线经十路南侧的泉城公园站(工程名),为地下水让路,车站浮出了地面。 e . - LE WE LEAR 46 2000 -11-19 大量元 ------------------ A TO S.T. are e . . . . . e adian Ba 2 C V.b.

人们常说：一条经十路，半座济南城。济南人的生活、出行，都离不开经十路。作为主要沿经十路敷设、贯穿济南东西的交通大动脉，济南轨道交通4号 线不仅是一条通勤线路，更是连接城市未来发展的纽带。 4号线全长40.3公里，共设站33座，全部为地下站，自西向东贯穿槐荫、市中、历下、高新和历城五大城区。它覆盖经十路沿线80%客流密集区域，是济 南轨道交通线路中里程最长、设站最多、工程体量最大的一条。作为备受关注的"黄金线路"，4号线不仅承载着便捷出行的期待，更藏着许多不为人知 的"城市密码"。今天，我们就来一场4号线车站的深度解密。 车站建设的极限挑战 在4号线的建设过程中，许多车站的建设各具特色，创下了济南轨道交通建设史上的多个纪录。 "最浅"：泉城公园站（以下均为工程名）是全线"最浅"车站，采用半地下设计，如同轻轻放置在公园里的艺术品。这座全国首例双曲薄壳混凝土结构地铁 站，在建设过程中向上抬升了7米，半地下设计还能让乘客在进出站时欣赏到公园美景，实现了交通功能与城市景观的完美结合。 "最难"：奥体中心站被建设者喻为全线"最难"的车站。这座车站施工时面临超浅埋、软土层、周边建筑密集等多重挑战，最终采用了济南首例"全暗挖 ...

调试工作分为车站调试和行车调试两大板块。车站调试涵盖通风、空调、给排水、动力照明等数十个系统；行车调试则包括信号、车辆、通信等核心系统 的联动运行。每一项都关系着未来列车的安全与准点。 最让人意想不到的挑战来自隧道内那些微不足道的细节。从最早进行的四站三区间的样板段调试时，整个机电系统部就全员进入隧道，展开"地毯式"排 查。 "列车高速运行会产生强大的活塞效应。"工程师孙久昊解释，"哪怕是一公分长的铁丝，一个被遗忘的螺丝帽，都可能成为安全隐患，我们要打起十二万 分精神检查。" 日前，济南地铁4号线空载试运行已正式启动，将于年底前建成通车。在这项庞大工程中，联调联试是确保运营安全的关键环节。一群被称为"地铁医 生"的联调联试工程师，日夜坚守在控制机房、轨道沿线及设备现场，以专业技术编织起一张看不见的安全网。今天，就让我们一同回顾济南地铁4号线联 调联试工程师们的攻坚故事。 40公里的 "地毯式" 排查 做安全的 "守护者" 去年8月起，宋增庆带领团队投入到了4号线的联调联试工作中。作为4号线联调联试负责人，他亲历了从第一个车站调试到全线贯通、空载试运行的全过 程。 "很多人认为我们的工作就是点点按钮，看看数据。 ...
