未来，地铁建设运营将更高效更绿色（新视点）

Group 1: Prefabricated Construction in Underground Spaces - Prefabricated construction is being increasingly applied in underground spaces, previously mainly used for above-ground buildings, to achieve green construction [1] - The example of the Guihua Station on Shenzhen Metro Line 22 shows a reduction in workforce from 150 to 32, a construction time shortening of about 30%, over 80% reduction in construction waste, and a carbon emission reduction of over 40% compared to traditional methods [1] Group 2: Addressing Geological Uncertainties - The use of advanced equipment like the muon imaging device allows for precise geological feature detection, providing critical decision support for safe construction [2] - The integration of automated systems and intelligent technologies is transforming subway construction from traditional building methods to intelligent manufacturing [2] Group 3: Intelligent Operations for Efficient Management - By the end of 2024, 58 cities in mainland China will have operational urban rail transit systems, making efficient operation a key challenge for many cities [3] - The development of artificial intelligence technologies presents new opportunities for subway operations, such as the autonomous repair robot developed by China Railway Scientific Research Institute [3] - In Shenzhen Metro, drones and high-precision panoramic cameras are used for automatic inspections, achieving a fault detection rate of over 93% for rail vehicle components [3]
