以某偏压联拱隧道为研究对象，借助有限差分软件 FLAC3D ，细化联拱隧道开挖歩序，对联拱隧道的开挖后围岩的收敛变形、应力分布进行分析。同时，针对中隔墙在联拱隧道施工及运营阶段所起的重要作用，分析了偏压作用下中隔墙的安全系数。根据计算结果提出结构设计及施工建议，其研究成果直接为工程服务，为今后类似工程提供借鉴。

In order to analyze the biased tunnel,the deformation and distribution of stress of sur-rounding rock are analyzed by using finite difference software FLAC3D .At same time,the safety factors of the mid-board are analyzed because of the important role of the mid-board in the con-struction stage and operation stage.Based on the results calculated by the software,the advices are offered to the design and construction,which can be directly applied in engineerning.And it can be used for reference in similar underground engineering.
