新建铜九铁路刘家湾隧道施工方案比选

Scheme Comparison of Liujiawan Tunnel for New Tongling-Jiujiang Railway

考虑到工程地质及后期运营安全,将原设计的路堑通过改为隧道通过,并由设计单位提出了4种方案。结合现场情况,通过方案比选,确定采用局部全断面法开挖、明洞法施工主体的方案。结果表明,该方案的实施保证了施工安全、质量及进度。

Considering engineering geological conditions and later operation safety,the original design of cutting changed to tunnel construction,and the design units proposed four schemes.Combined with construction site and schemes comparison,the scheme of partial whole section excavation and open-cut tunnel for main construction body are adopted.The results show that the application of this scheme ensures construction safety,construction quality and construction time.
