Exploration of Flood Risk Cause Identification and Prevention and Control Strategy of Subway Underground Construction in Coastal Areas

This paper explores the identification of flood risk causes and prevention and control strategies for subway underground construction in coastal areas. With the backdrop of global climate change leading to increased frequency and intensity of extreme weather events, the construction of rail transit engineering, especially in coastal cities, faces significant challenges. The paper discusses the high-risk nature of subway construction due to the complex underground environment and the lower skill threshold of construction personnel. It reviews the current status of risk management research both domestically and internationally, highlighting advancements in risk identification, assessment methods, and intelligent construction management. The study emphasizes the need for a comprehensive approach to flood risk management, including risk identification, assessment, and disaster prevention planning, as well as the improvement of flood disaster prevention and control systems. The paper concludes by advocating for the optimization of engineering design, construction adjustments, and the establishment of a long-term monitoring and maintenance mechanism to enhance the resilience of coastal cities' subway construction against flood risks.
