隧道软弱破碎带围岩施工技术

Construction Technology of Fracture Zone of Surrounding Rock for Weakly Tunnel

软弱破碎带的围岩是进行隧道施工的特殊环节,应合理使用整体施工技术处置隧道的软弱破碎带围岩。对隧道软弱破碎带围岩CRD施工方式进行介绍,阐述隧道软弱破碎围岩进行开挖的过程,并对其进行实时的监测,利用了工程实例分析相关技术。

This part of the weak broken zone can be said to be a very special part of the tunnel construction. Therefore,in the tunnel excavation,should be a reasonable use of the scientific construction of the overall construction technology to use this construction technology to the tunnel of the soft surrounding rock to give special treatment. This paper mainly introduces the construction method of CRD in the surrounding rock of the tunnel. This paper expounds the excavation process of the soft and broken surrounding rock of the tunnel and carries on the real-time monitoring to it.
