摘　　要：针对大坡度富水隧道斜井反坡排水的技术难题,以黎霍高速太岳山隧道1号斜井为依托工程,结合工程水文地质条件,提出反坡排水的基本原则,基于地下水动力学理论计算隧道排水量,确定不同隧道段的富水等级,结合隧道排水管路沿线损失及局部损失情况,确定具体排水设备型号,制定详细的隧道洞口污水处理方案。相关研究成果可为类似隧道工程的反坡排水施工提供指导和参考。Focusing on the technical difficulties of the backslope drainage for the inclined shafts of the water-rich tunnel with a large slope gradient,this paper studied the inclined shaft No.1 of Taiyue Mountain Tunnel in Lihuo Expressway.The basic principle of backslope drainage was proposed combined with the engineering hydrogeologic conditions,the water-rich class of different tunnel sections was determined based on the tunnel drainage calculated by the theory of underground dynamics,and the specific drainage equipment models were determined according to the loss along the tunnel drainage pipeline and local losses.A detailed tunnel hole sewage treatment plan was developed and the research results can provide guidance and reference for the backslope drainage construction of similar tunnel engineering.
