Group 1: Prefabricated Construction in Underground Spaces - Prefabricated construction is being increasingly applied in underground spaces, previously mainly used for above-ground buildings, enhancing efficiency and sustainability [1] - The example of the Guohua Station on Shenzhen Metro Line 22 illustrates that prefabricated construction can reduce the workforce from 150 to 32, shorten construction time by approximately 30%, and decrease construction waste by over 80% [1] - Carbon emissions are reduced by more than 40% compared to traditional methods, achieving green, low-carbon, and quality-enhancing goals [1] Group 2: Addressing Geological Uncertainties - The development and utilization of underground spaces face geological uncertainties, which are being mitigated by advanced technologies [2] - The Muon Imaging technology provides detailed geological feature detection, acting as a "perspective eye" for underground construction, identifying hidden voids and weak strata [2] - A range of intelligent equipment, including autonomous detection vehicles and integrated smart tunneling machines, is transforming construction from traditional methods to intelligent manufacturing [2] Group 3: Intelligent Operations for Efficient Management - As of the end of 2024, 58 cities in mainland China will have operational urban rail transit systems, necessitating efficient management of these systems [3] - The development of artificial intelligence technologies presents new opportunities for metro operations, exemplified by the first mobile intelligent heavy-load repair robot for rail transit developed by the China Railway Science Research Institute [3] - In Shenzhen Metro, drones conduct automatic inspections, and high-precision cameras record inspection data, achieving a fault detection rate of over 93% for rail vehicle components through deep learning and AI technologies [3]

装配式建造能否走进地下空间？全国超1.2万公里地铁，如何实现智慧运营？日前，地铁创新发展国际 学术交流会在深圳举办，与会专家们描绘了全球地铁的未来发展图景。 以装配式建造实现绿色化。 地铁车站也能拼出来。走进深圳地铁22号线桂花站，随着智能龙门吊缓缓推进，一片片混凝土构件被精 准放置到位，一座地铁车站随之成型。"装配式建造作为一种现代建筑技术，之前主要用于地面建筑， 近年来逐步被应用到地下空间。"国际隧道和地下空间协会前主席严金秀告诉记者，装配式建造的关键 在于流水线上"做"配件，"搭积木"式造建筑，实现标准化设计、工厂化生产、装配化施工、信息化管 理。以桂花站为例，作业人员由150人缩减为32人，缩短工期约30%，建筑垃圾减排超80%，碳排放总 量较传统工艺减少超40%，达到了绿色低碳、提质增效的目的。 (责编：袁勃、赵欣悦) 关注公众号：人民网财经 开发利用地下空间，要面对不少不确定性。如今，这一情况正在改变——在深圳地铁25号线一期工程现 场，一个方形机械柜很是显眼。它所到之处，地质特征被探测得一清二楚。这便是缪子成像仪，可根据 不同地层密度区对缪子的吸收差异进行成像。在智能算法驱动下，它化身为地下施工 ...
