Underground engineering Laplace transform Modified Peck formula Settlement Winkler foundation model

摘要：

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
