| Abstract: | Taking the section of SK8 ＋ 414 -SK8 ＋ 451 between the west bridge station and Jiaohua square in the first line of rail traffic in Harbin as a project example, this section is the using part of existing 7381 tunnel, which crosses underneath the Binsui railway and west bridge. Both the technologies of ground reinforcement for existing railway and tunnel section and single-side construction for expansive excavation reconstruction were mainly introduced for the complicated condition, which could provide similar project of underground railway construction with reference. |
