Strength analysis of cable tunnels with different embedding depths by using finite element method

The present paper establishes a three-dimensional solid model of cable tunnel. Considering both the engineering cost and safety, different cross-sectional forms and sizes are proposed firstly. Then the finite element method is used to analyze the strength and deformation of the structure under different embedding depths. Finally, a better cross-sectional shape is chosen under the premise of safety and cost by comparing the results. The results can be used as a reference to the design of actual engineering structures.
