| Abstract: | The portal pear with steel beam and concrete column is used to decrease the span, reduce the height of the structure and shorten the time of when newly built railway crossing the existing railway. With the portal pear of WUSongXisuper large bridge in HuNing inter-city railway as a practical engineering example, the structure characteristics and the construction scheme of this portal pear with steel beam and concrete column was discussed in this paper. |
