Tunneling beneath Existing Buildings Supported on Shallow Foundations
The traditional modification factor approach employed to evaluate the building movements due to tunneling is for plane-strain situation. Such approach could not cater for the effect of building dimension along the tunnel axis. In the present study, three-dimensional finite element analyses were conducted to determine the movements of buildings with various plan dimensions and locations induced by tunneling. A new modification factor is proposed to cater for the true three-dimensional nature of the problem. A relationship between the new modification factor and building bending stiffness is proposed to determine the relative movement between the shallow foundation and Greenfield ground settlement due to tunneling.
