摘要
双向六车道公路隧道跨径较大,洞身较为扁平,受力体系不稳定,加之洞口段围岩较差,浅埋偏压极易发生,给施工带来较大安全隐患。以花山隧道为例针对双向六车道公路隧道进洞处理方法进行探究,以供参考借鉴。
The two-way six lane highway tunnel with large span,the hole is relatively flat,the stress system is not stable,coupled with the surrounding rock of the tunnel is poor,shallow buried bias is very easy to happen,to bring the construction of a large security risk.The Huashan tunnel as an example for the two-way six lane highway tunnel into the hole processing methods of inquiry,for reference.
