| Abstract: | The risk factors for the construction of a Metro station built by enlarging the shield-bored tunnel are analyzed on basis of the preliminary design,surrounding environment,engineering geological conditions,hydrological conditions,excavation procedure and structural stress re-distribution of the Metro station.Then,countermeasures are proposed.In addition,the key points of monitoring measurement for critical construction positions and critical construction procedures are analyzed.This paper can provide reference for the risk analysis and control of similar projects in the future. |
