This paper is to study the feasibility and mechanical properties of the tunnel trolley in Yangdan mountain. Analyze the internal force and deformation of the trolley and template with the ABAQUS, and the results show that the internal force of the model is much less than yield stress. Therefore, the structure is very safe.

The Sujia Road Bridge is under the construction,in order to ensure the construction will not have template problems,numerical simulation is needed.Analyze the internal force and deformation of the bridge pier template with the ABAQUS,and the results show that the internal force of the template is much less than yield stress.Therefore, the structure of the template can be optimized.
