Environmental Risk Source Analysis and Classification of Zones: Subway Construction

Examining the environmental risk sources of regional subway construction is crucial for ensuring safety and providing guidance future line planning. This study focused on Urumqi’s main urban area used SBAS-InSAR analysis technology to extract settlement rate field within 600 m Urumqi Metro Line 1 investigate these sources. Results showed that affecting in could be classified into four categories: geological conditions, distribution high-rise buildings, density road networks, clustered buildings. The further analyzed spatial each source developed a comprehensive impact zoning evaluation model area. was then assess currently planned lines (1–7), revealing largest (1444 partitions) associated with soil layer, IV building risk, network risk. Additionally, found had most significant 6, emphasizing importance closely monitoring factors during construction.
