Abstract

Abstract: The connected-arch tunnel is of big span .Since the mutual influence of each working procedure and complicated strength of the construct accepted during construction , a reasonalbe choice of the construction plan and method of dig can obviously reduce the cost of the temporary protected system , and ensure the tunnel safety during construction and using .

Key words: connected-arch tunnel , tunnel , construction

摘要： 连拱隧道跨度大，施工过程中由于各工序互相干扰，结构受力复杂，合理选择施工方案和开挖方法能明显降低临时支护成本，确保隧道结构在施工及运营期间的安全

关键词: 连拱, 隧道, 施工
