Abstract:
Based on Winkler elastic foundation beam theory, Peck modified formula and Laplace
transform are used to solve the approximate differential equation of the deflection curve. The
settlement calculation method for important homogeneous structures where the tunnel passes
underneath is studied. The analytical solution for the settlement of the homogeneous structure
is derived and verified. The field monitoring and numerical analysis results are compared.
Laplace transform method requires fewer parameters to solve the approximate differential
equation of the deflection curve, and its calculation efficiency is high, and the result is the
same as that of the classical literature. The method can be applied to practical engineering,
and satisfactory results can be obtained. The analytical process in this paper provides a
reference for solving similar problems, and the solution can be used for ground settlement and
providing an early warning for settlement when the underground engineering passes through
the important homogeneous structure from below
