Influence of Tunnel Excavation on the Deformation of a Frame Building

Tunnel excavation inevitably causes surface deformation. In urban areas, deformation could lead to the of surrounding buildings, which may cause damage communities when accumulated a certain extent. However, current construction organization and management mainly rely on on-site measurements, there is still lack reliable prediction methods. Here, we proposed an effective evaluation method for frame building based stochastic medium theory equivalent beam theory. This effectively evaluate after horseshoe tunnel by considering non-uniform convergence. Furthermore, its accuracy practicability were verified using Nanyan Fourth Circuit Transmission Reconstruction located in Dalian, China. The results show that spatial distribution characteristic values maximum tensile strains closely related ratio Young’s modulus shear (E/G), height (h), depth (H), tangent influence angle (tan β) convergence radius (ΔR). These achievements can provide theoretical basis analytical ideas investigating shallow buried structure buildings cities.
