Hazards threatening underground transport systems

摘要: Metro systems perform a significant function for millions of ridership worldwide as urban passengers rely on secure, reliable, and accessible underground transportation way their regular conveyance. However, hazards can restrict normal metro service plans to develop or improve set aside some cope with these hazards. This paper presents summary the potential worldwide, identifying knowledge gap understanding water-related impacts networks. is due frequency scope geotechnical air quality hazards, which exceed in extreme magnitude precipitation events that influence systems. Thus, we emphasize importance studying fill gaps this topic.
