| Abstract: | In combination with example of supervision and measurement on expansion construction site of Yuzhou Tunnel with extra large section,this paper expatiates differences of expanded tunnels from general new tunnels via analysis for monitoring data of surface subsidence,arch top settlement and peripheral displacement,and proposes construction methods suitable for expanded tunnels and construction time of secondary lining based on these differences.Based on analysis for monitoring data of internal force of steel ... |
