摘 要: 针对客运专线铁路隧道软弱围岩地质区段多的特点,对软弱围岩的工程地质特征、软弱围岩隧道变形特征和表现形式进行了分析,从超前地质预报与预加固、施工方法选择、初期支护施工以及围岩监控量测等方面提出了软弱围岩隧道的安全施工方法和应对措施,对于保证隧道施工安全具有重要意义。 For passenger dedicated line tunnel with soft surrounding rock engineering geological characteristics, the soft surrounding rock tunnel deformation characteristics and manifestations are analyzed. With advanced geological forecast with pre-reinforcement, choice of construction methods, initial support construction and rock monitoring and measurement, the paper proposes soft surrounding rock tunnel construction safety methods and counter measures, which plays a important and significant role to ensure tunnel construction safety.
