摘要
连拱隧道左右洞之间仅一墙之隔,在围岩较差的地质条件下针对采取的开挖支护顺序,着重在受力分析角度为开挖顺序决策提供科学依据,为施工类似工程项目提供决策依据。
The double-arch tunnel is separated by one wall. Under the bad surrounding rock geological condition,based on the used excavation support sequence,the force analysis is done to supply science basis for excavation sequence.
