Abstract
The application relates to a mismatched grid mapping method of a variable stratum and a tunnel numerical model, and relates to the field of tunnel structure probability analysis in uncertain strata, in particular to an automatic mapping method for solving the mismatch of the variable stratum and the grid of the tunnel numerical model. The mismatched grid mapping method of the variable stratum and the tunnel numerical model established by the application can preferably consider the problem of the mismatch of the regular grid in the simulation of the variable stratum and the distorted grid in the tunnel numerical model, and through the method, different soil types of the grid unit of the variable stratum can be automatically mapped into the tunnel numerical model, thereby providing technical support for the subsequent research on the stratum variability and the stress and deformation analysis of the tunnel structure.
