Assessing Failure Risk of Existing Metro Stations During Unilateral Large-Scale Excavation: An Experimental and FE Perspective
Introduction Urban rail systems are lifelines in modern cities, yet their safety can be challenged when nearby large-scale excavations unfold. This article synthesizes experimental insights and finite element (FE) analyses to understand the failure risk of existing metro stations during unilateral, large-scale excavation. Drawing on established research in soil-structure interaction and case studies from major…

Failure Risk of Metro Stations During Unilateral Large-Scale Excavation: A Geotechnical Perspective
Introduction The stability of existing metro stations under nearby construction is a critical concern for urban infrastructure. When unilateral large-scale excavation occurs adjacent to underground transit facilities, the surrounding soil-structure system experiences complex stress changes that can elevate the risk of station or tunnel failure. This article synthesizes findings from experimental studies and finite element…
