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…

Experimental Insights into the Failure Risk of Existing Metro Stations Under Unilateral Large-Scale Excavation
Introduction Urban metros are vital arteries of modern cities, but their long-term performance can be challenged by large-scale ground works nearby. A growing body of research examines how unilateral excavation—where the soil is removed on one side of an underground structure—affects the stability and serviceability of adjacent metro stations. This article synthesizes experimental findings and…
