Trickling water frequently occurs in the outside appearance of biconnected arch tunnels after the secondary lining, influencing their construction quality and operating.
在双连拱隧道施工中，二次衬砌完成后表面往往会出现渗漏水现象，对双连拱隧道施工质量及营运造成影响。

For a secondary bifurcation buckling load, the limit load carried capacity of the arch of 0.1 rise-span ratio is the biggest one under a full span load distribution.
全跨均布荷载作用下，矢跨比0.1的拱极值点屈曲和二次分岔屈曲极限承载力均大于其他拱。

As the large spanned arch tunnel is influenced by the structure and span, the loads on initial support and secondary lining are different.
