Abstract
Because the landslide has an important influenceon the internal force and deformation of the existing tunnel, andthe research on the stress and deformation of the tunnel in thelandslide area tends to field engineering monitoring, thecorresponding theoretical analysis is relatively small, and thereare some defects. First, Pasternak two parameter foundationmodel is introduced to establish the elastic foundation beammodel of tunnel landslide interaction, which solves the soildiscontinuity of Winkler foundation in the previous theory, andthe transfer matrix method is used to derive the transfer matrixformula. Then, Matrix Laboratory (MATLAB) is used tocompile the corresponding calculation program to analyze thedistribution characteristics of internal force and deformation ofthe tunnel. Finally, the influence of relevant parameters such asthe elastic coefficient of foundation inside and outside thelandslide deformation area, the magnitude and distribution oflandslide thrust, and the foundation shear stiffness inside andoutside the landslide area are analyzed.
