Research on Surface Settlement and Deformation of Buildings Caused by Double Line Tunnel Mining Method Construction
Taking the construction of a separated double-line mine tunnel in Fuzhou as the background,a tunnel underpass building model is established by numerical simulation to study the surface settlement characteristics during construction and the distortion of the building af-ter the tunnel passes through the building at different angles.The results show that the surface settlement increases greatly at the monitoring section;The surface settlement value in the influence area of the building is larger and steeper than that under the same tunnel depth condi-tion without the building.When the Angle between the building and the tunnel excavation axis is 30°,the maximum surface settlement value is obviously larger than that at other angles.The greater the Angle between the building and the tunnel excavation axis,the greater the dis-tortion of the building and the greater the damage to the building.
