Research conclusions: There are the big differences in the culvert design，layout of bridge deck，calculation of train braking force and traction force，braking force on pier of continuous beam bridge，distribution of braking force，limited value of deformation of creep on beam，calculation method of pile foundation and principles of reinforcement of pile cap between China Railway and German Railway．Through communication and discussion，the reasons for the differences are known and the reasonable opinions of German experts are listened to，which can provide the reference to improving the construction quality of bridge and culvert in China．
