新华社深圳8月22日电(记者毛思倩、陈宇轩)记者22日从深圳地铁集团获悉,该集团近年联合华北电 力大学、西北工业大学深圳研究院,将缪子成像技术深度融入到多条地铁、城际铁路等轨道交通线路施 工全流程中,如同为盾构隧道拍"CT"一样,为我国轨道施工地下空间探查及灾害防控提供了新的思路 和方法。 缪子是一种基本粒子,宇宙射线里的高能缪子可以穿透岩石和金属,揭示地下世界的秘密。深铁集团工 程技术中心负责人介绍,缪子成像具有穿透能力强、空间分辨率高等特点,可根据不同地层密度区对缪 子的吸收差异特性进行成像,能应用于地下深层结构密度缺失区探测,就像"天然的地质探针",帮助工 程技术人员看清地表之下的结构。 中国科学院高能物理研究所研究员、中国散裂中子源缪子源实验站负责人鲍煜表示,近年来,缪子成像 技术日益成熟,利用该技术进行内部结构的勘探就是其重要的应用场景之一,在采矿、地铁建设方面可 以发挥重要的作用。 据有关负责人介绍,该技术的应用源于2024年初深圳地铁16号线共建管廊项目在施工中遭遇难题:面对 近20米厚的复杂地层与交错密布的地下管线,传统钻探勘探仅能覆盖浅层区域,难以探明深层地质全 貌。为了破解"地下迷局",深 ...
