摘要
双跨连拱隧道的施工难点之一是分部开挖过程中的爆破振动影响，博山2号隧道左导洞开挖时对中导洞的爆破影响进行了观测，得出一些有益的结论，为类似工程的施工提供了依据。
The difficulty of construction of continuous-double-arch tunnel is the blasting effect. This paper analizes the measuring data of vibration effect on middle pilot caused by blasting excavation of left pilot of Boshan No. 2 tunnel. Some beneficial conclusions are obtained which are a good reference to similar projects.
