Wucun tunnel underpasses intensive buildings with high-risk characteristics such as ultra-shallow,large-span,complex construction process,high-protection demand on buildings in Xiamen City,and dynamic feedback analysis method is carried out during tunnel construction process in complex geological and environmental conditions. The monitoring measures for the safe construction of the tunnel mainly include building settlement,surface subsidence,building inclination,the tunnel vault subsidence,tunnel adjacent formation restraining,the soil body depth portion displacement,the soil body lamination subsidence,blasting vibration,subsoil water level and so on,especially static level sensor is applied to the important buildings for automatic monitoring. In accordance with ISO9001 quality certification system,a sound and efficient operation system is established in the feedback analysis process. Based on construction experience of city tunnel and the results of preliminary researches in Wucun tunnel,monitoring is carried out on the surrounding environment as well as on tunnel structure itself. In addition to routine monitoring tools,advanced technology such as automatic monitoring on differential settlement of buildings,monitoring information management and prediction systems,monitoring information feedback by LAN and WAN,early-warning facilities by desktop alarm systems and electronic display boards,are applied to dynamic feedback analysis throughout tunnel construction;so that the feedback analysis work has distinctive informationizing characteristics in Wucun tunnel engineering.
