Abstract

To close the railway construction of both the impact of highway operation safety, from both the highway embankment and excavation slope section and the distance between the supporting structure in recent slope height maximum cross section of a typical cross section, the numerical simulation analysis method is used for modeling analysis of rock mass and supporting structure model is constructed, the construction process is simulated, The deformation law of support structure, rock and soil mass of slope and existing highway subgrade during construction is obtained. It provides a theoretical guarantee for the safety of existing expressway and subgrade slope during railway construction.
