Abstract:Aiming at the problem whether the internal force and displacement of template of secondary lining trolley of Yangdanshan tunnel meet the current standards and requirements during the pouring of concrete, the simulation and calculation were performed with numerical simulation software ABAQUS.In addition, the actual measurement was performed in the construction site,the measured lateral pressure was imposed on the model,and the internal force and displacement results were obtained.The calculated and measured results show that the position for the biggest template radian change will suffer the biggest pressure.The connection parts between the connection plate and rib plate as well as between the trolley structure and connecting rod are the weakest sites in the whole structure,and therefore enough strength should be ensured in each connecting part.The rib plate in the connecting part plays a very important role in limiting the template deformation.
