| Abstract | Simple closed-form complex variable solution is presented for the prediction of the tunneling-induced ground movements of a circular tunnel in soft ground. The solution is derived by using the conformal mapping technique and the Laurent series expansion of analytic functions. The boundary conditions of a uniform radial stress and a uniform radial displacement at the tunnel opening are considered. The oval-shaped ground deformation pattern is also considered by imposing as the boundary condition at the tunnel opening. The difference between uniform radial and oval-shaped ground deformation patterns on ground deformations is investigated. The applicability of these proposed analytical solutions is then checked with five case records, which encompass a range of ground conditions from very stiff to soft clays, and compared with other approximate solutions. Generally good agreement of the predicted ground deformations can be seen with field observations for tunnels in uniform clay. |
