On the other hand, although national conditions differ, structure types also differ greatly (take small and medium-sized span concrete girder bridge as an example, the prefabricated girder is commonly adopted in the United States on which cast-in-situ concrete deck is then added, while the prefabricated girder is commonly adopted on which pavement is then added in China) , but in recent years the progress has been achieved in bridge engineering technology are mainly analyzing and calculating methods, while the progress in the foundation design theory and material is relatively limited.
