摘要
本文结合贵广铁路坡白山隧道软弱围岩段支洞进主洞时,采用横向棚架法进行进行隧道软弱围岩交叉口段施工,具有挑顶距离短,爆破频率低,对围岩扰动少,工序简单,施工快捷,经济合理等特点。
When a branch tunnel of Guizhou-Guangzhou Railway enters the main tunnel, the crossing section of tunnel soft surrounding rock is constructed by transverse framing method, with the characteristics of short roof-lifting distance, low blasting frequency, less disturbance to surrounding rock, simple procedure, fast construction and reasonable economy.
