摘　　要：以沿海某环岛路连拱隧道为依托,采用有限元数值模拟的分析方法,考虑隧道所处的特殊地质条件,模拟隧道开挖的施工全过程,得出了隧道与上部地面建筑物的竖向位移云图,以及隧道自身结构的主应力云图,计算结果表明,采取设计拟定的工程措施,可以保证隧道施工过程中地面建筑物与隧道自身的安全.同时,在隧道施工中,必须对隧道进行动态施工监测管理和安全隐患预报.Based on the two arch tunnel in coastal city , and combining the methods of finite element numerical simulation with the special geological conditions of tunnel , the whole process of the construction of tunnel excavation was simulated in this paper .The vertical dis-placement nephogram of tunnel and the upper part of the buildings on the ground was ob -tained involving the principal stress nephogram of tunnel structure .The calculation results showed that taking designed engineering measures could ensure safety of the buildings on the ground and the tunnel .During the construction , the need for dynamic monitoring of construc-tion management and safety hazard prediction of tunnel .
