摘要
针对高速公路隧道岩溶、断裂地段出现的初支侵限、涌水问题,以光山1号隧道为依托,对地质条件复杂,为了保证施工安全及工程质量,通过采取引排水、径向注浆小导管、超前大管棚、空腔封堵、侵限换拱等有效措施,合理安排先后施作顺序,对出现的围岩变形、突发涌水等情况进行了有效控制处理,为后续施工奠定基础.
Abstract
This paper analyzes the problems of initial support intrusion and water influx in karst and fractured sections of expressway tunnels,using Guangshan No.1 Tunnel as the background.In order to ensure construction safety and engineering quality,effective measures such as drainage,radial grouting small conduits,advanced large pipe sheds,cavity sealing,and arch replacement were taken to reasonably arrange the sequence of construction.The deformation of surrounding rock and sudden water inflow were effectively controlled and dealt with,laying the foundation for subsequent construction.
