摘要
文章以郑万高铁9标工程为例,该工程成功应用10台三臂凿岩台车进行钻爆法开挖施工,特别是在兴山隧道出口段,成功应用于Ⅳ、Ⅴ围岩大断面隧道全断面开挖施工,为今后类似工程提供了借鉴。
The article takes the Zhengwan high-speed railway 9 standard project as an example.This project successfully applied 10 three-arm rock drilling rigs for drilling and blasting excavation,especially in the exit section of Xingshan tunnel,and successfully applied to large sections ofⅣandⅤsurrounding rocks.The full-section excavation of the tunnel provides a reference for similar projects in the future.
