| 摘 要： | 针对筲箕湾连拱隧道的开挖过程进行两种不同工序的模拟计算，计算中墙在两种不同开挖工序下的强度、变形与稳定性，比较不同开挖工序对隧道中墙的影响。结果表明，中墙是连拱隧道最主要的受力构件，非对称开挖容易在中墙上引起较大偏心荷载。根据计算结果来评价开挖工序的优劣，对连拱隧道的开挖过程提出一些建议。

| Abstract: | Simulating computation for Shaojiwan double-arched tunnel about two different excavating sequences is carried out; and pays attention to strength, displacement and stability of effects under two excavating sequences. The results show that the mid-partition is a key load-carrying member; the nonsymmetrical excavating will bring eccentrically loads on the mid-partition easily. From the computing results, this paper evaluates the excavating, and gives some opinions on excavating procedure of double-arched tunnel. |
