posted on 2012-07-31, 13:21 authored by Quinhua Lin, Victor V. KrylovA theoretical model has been developed of generating ground vibrations by
underground trains travelling in idealised circular tunnels of finite diameter. By
means of the reciprocity principle, the displacement field radiated by a point
force applied to the bottom of the tunnel, i.e., the Green's function of the
problem, has been derived in zero and first approximations versus tunnel
diameter. This more precise Green's function has been applied to carry out
calculations of railway-generated ground vibrations testing earlier developed
methods. The results show that the velocities of generated low-frequency
ground vibrations increase with the increase in tunnel diameter. It is also shown
that zero approximation is accurate only at very low frequencies.
