Calculation of Building Foundation Settlement Caused by Shield Tunnel Construction
The formation of settlement troughs for the case when there are buildings above a tunnel is different from the case without buildings present on the ground surface during construction of shield tunnels below the ground. By considering the influence of building stiffness, previous studies have calc...

The formation of settlement troughs for the case when there are buildings above a tunnel is different from the case
without buildings present on the ground surface during construction of shield tunnels below the ground. By considering
the influence of building stiffness, previous studies have calculated the surface of building subsidence during shield
construction, but it was assumed that the soil around the tunnel would shrink evenly toward the center and that the focus
should be fixed and the foundation stiffness of the building was not considered. The method used in this paper modifies
the forward method, by considering a uniform ground movement model for shield tunnels and the foundation stiffness
and depth. The calculated values are compared to the measured values, the values of the other method and also values
obtained using finite-element simulation. The effects of the equivalent elastic modulus of buildings E1, the depth of the
tunnel axis from the ground h and the distance between the tunnel axis L to the settlement of foundations are also
analyzed. The results show that the values obtained by the present calculation method are more similar to the measured
and finite-element simulation values than the values obtained using the other method. The settlement of foundations is
found to decrease with increasing E1, h and L. |
