隧道施工过程中极破碎围岩整治初步探究

Research preliminary on the control of extremely broken surrounding rock in the tunnel construction process

以云南某公路隧道工程为例,针对隧道施工过程中极破碎围岩的整治方法进行了探讨,详细介绍了极破碎围岩条件下施工方法及相关技术指标,并提出施工要点,对类似隧道工程施工具有一定指导意义。

Taking a highway tunnel project in Yunnan as example,according to the control methods of extremely broken surrounding rock in the tunnel construction process made discussion,this paper introduced in detail the construction methods and the relevant technical indexes in the conditions of extremely broken surrounding rock,and put forward the construction key points,had certain guiding significance to similar tunnel construction.
