厦门公路做“CT” 检测车“巡诊”地下隐患_我的网站

一 |     Drones zip across city blocks, delivering meals to doorsteps. On factory floors, humanoid robots are put to the test. Streets buzz with electric vehicles, and artificial intelligence (AI) is woven ever deeper into manufacturing, healthcare and urban services.        When China hosts the 33rd APEC Economic Leaders' Meeting in Shenzhen this November, delegates will gather in a city that has become one of the country's leading centers for emerging industries. It will be China's third time hosting the event, following Shanghai in 2001 and Beijing in 2014.    Adjacent to Hong Kong, Shenzhen in Guangdong Province was one of China's first special economic zones and has evolved over the past four decades into a global hub for innovation and advanced manufacturing. It is home to tech heavyweights such as Huawei, Tencent, BYD, DJI, and UBTECH, along with a vibrant community of startups spanning sectors from AI to new energy.    In the first half of 2026, the city's trade with other APEC economies rose 33 percent to 1.98 trillion yuan (about 291.6 billion U.S. dollars), accounting for 68.8 percent of its total foreign trade. Today, Shenzhen offers a window into China's new growth drivers and their potential to create new opportunities across the Asia-Pacific region.    LOW-ALTITUDE ECONOMY    Official data show that around 70 percent of China's consumer drones and half of its industrial drones are produced in Shenzhen, home to leading manufacturers including DJI.    Shenzhen is also a testing ground for commercial drone applications, from logistics and emergency response to power-grid inspection.    Food-delivery giant Meituan opened its first drone-delivery route to customers in Shenzhen years ago. By the end of June 2026, its drones were delivering orders from over 1,500 merchants, including KFC, McDonald's and Chinese tea chain Chagee.    To support the industry's growth, Shenzhen has built more than 1,200 low-altitude takeoff and landing facilities and opened 310 logistics routes. Cargo drones completed more than 1 million flights in 2025, up 29 percent from a year earlier.    Shenzhen has also led the way in regulation. In 2019, it became the first city in China to introduce local legislation specifically for the management of civilian light and micro drones.    NEW ENERGY VEHICLES    Shenzhen has emerged as one of China's leading hubs for new energy vehicles (NEVs), backed by strong innovation capabilities and one of the country's most complete industrial ecosystems spanning lithium battery materials, energy storage integration and end-use applications.    One of the best-known companies benefiting from this ecosystem is BYD, headquartered in Shenzhen. The automaker sold around 2.26 million electric vehicles (EVs) in 2025, surpassing Tesla in global EV sales last year. Its NEVs are now available in 119 countries and regions.    The city is also home to more than 1,400 intelligent-driving companies.    Shenzhen is investing heavily in charging infrastructure. In 2023, it launched a drive to become a "city of superchargers," and by 2024, supercharging facilities outnumbered conventional petrol stations. So far, it has built more than 1,200 ultra-fast charging stations with charging power of 480 kilowatts or above.    ROBOTS AND AI    Last year, a robot 6S store, claimed to be the world's first of its kind, opened in Shenzhen and quickly became a local sensation.    Shenzhen has fostered a new generation of robotics companies, including UBTECH, Honor and Leju Robot. By the end of 2025, the city was home to 34 listed robotics companies and nine unicorns.    The sector expanded rapidly last year. Humanoid robot production surged 83.1 percent year on year to 343,400 units, while the total robotics industrial output value in the city exceeded 240 billion yuan, up over 20 percent year on year.    Shenzhen has more than 2,600 major AI companies, with an industry spanning AI chips, algorithm frameworks and foundation models as well as software and hardware applications.    AI-enabled smartphones, translation earbuds, smart glasses and smart toys made in Shenzhen are increasingly reaching both domestic and overseas markets.                    。    AI摘要      厦门近日启动道路“地下体检”，利用三维雷达检测车对58条主干道开展无损探测，无需封路。

二 | 预计9月底出具报告，精准排查空洞、脱空等隐患，保障城市道路安全运行。

三 |               三维雷达检测车在湖里区滨海路探测地下病害。    三维雷达检测车缓缓驶过，作业无须封路，市民如常通行，道路地下的“CT影像”正在一帧帧生成。    近日，厦门开展道路“地下体检”，共覆盖58条主干道路，车道里程约2300公里，环岛路、环岛干道、滨海路、翔安大道、集美大道均在检测范围内。    市交通局公路中心表示，预计9月底能拿到“CT报告”，排查出空洞、脱空隐患等道路病害。    地下3米全“看得见”     在湖里区滨海路，一辆黄色小车正缓慢行驶，后方警示灯不停闪烁。车尾离地不到10厘米处，托着一个长方体的装置，车身标有“随时停车”“地质病害检测车”字样。“就像医院做CT一样，我们用雷达给地下做检测，地下3米全‘看得见’。”检测车内，检测员小何的眼睛几乎没离开过面前的屏幕。屏幕上是一条不断向前延伸的彩色波形图，像一张被拉长的心电图。“这就是地下的‘照片’。”小何指着屏幕说，车载三维阵列雷达以200兆赫兹的频率向路面以下发射电磁波，遇到土体密实度变化，比如空洞、脱空、疏松体、富水体，波形就会出现异常反射。    车外，一辆防撞缓冲车始终尾随，爆闪灯在日光下一闪一闪。

四 | “这是标配，每辆检测车后面都得跟着一辆。”市交通局公路中心直属公路部门工程师陈志勇说，作业时安全防护一刻不能松。    一天检测近100公里     城市道路地下管线错综复杂、地质条件多变，受管涵施工、地下水渗流等多重因素影响，道路路基薄弱区域易出现空洞、脱空等隐蔽病害。    “以往依靠人工目视巡查、图文记录等方式，无法排查地下深层隐患。”陈志勇介绍，如今依托地质病害检测车等智能检测设备，车辆行驶即可精准探测地下病害，检测效率与精准度大幅提升。    “一辆检测车一天能跑80到100公里。

五 | ”检测公司技术人员毕翔介绍，岛内岛外多辆检测车同步分段推进。车流相对平稳的道路，安排在白天作业；而长岸路、环岛干道会展段、嘉禾路、厦门大桥段这些车流量大的特级主干道，全部留到夜间。但不是所有天气都能作业。雨天、台风天、汛期强降雨必须停工——雨水会吸收电磁波，探测精度直接打折扣。    三年周期覆盖全域公路     检测车跑一遍，只是第一步。

六 |     “雷达画面只记录轨迹和路面影像，没法实时识别空洞，需要靠后期人工判读。”毕翔介绍，检测车采集到的数据要带回公司，用专用软件逐帧解析，人工复核每一段波形，标记出疑似空洞的位置、范围和体积，形成靶向病害台账。标记出的隐患点，还要用手推式二维雷达上路二次复测。“车载的是初筛，手推的精度更高，用来定点确认。

七 | ”毕翔说，最终完整的检测报告交付市交通局公路中心，为后续维修处置提供科学依据。    陈志勇告诉记者，从2021年起，市交通局公路中心每年委托第三方开展道路“空洞”检测，实行三年一轮全域全覆盖——三年周期内，辖区所有县道、乡道至少完整检测一遍，高等级道路单周期内可检测2到3次。

八 | “通过对比历年数据，可对病害发展趋势进行动态追踪和提前预警。

九 | ”陈志勇说。    市交通局公路中心相关负责人表示，将依托现代化检测手段、落实科学修复方案，全力保障道路通行，为市民打造平稳、安全的出行环境。（厦门日报记者 林钦圣 通讯员 林萍 文/图 ）。
