摘要
超前支护是隧道施工中穿越软弱、破碎围岩的一种有效的加固施工方法,但由于设计主要依赖于工程经验,不能预测支护效果。通过分析超前小导管在不良地质隧道中的支护机理与理论,对红石沟隧道工程用FLAC3D软件数值模拟,论证了超前小导管技术在隧道施工中的合理支护效果。
The small-lead-tube advanced slip-casting method is a widely used method fir tunnels in the broken and/or soft rock masses. However, its supporting results could not be theoretically predicted since its design is empirical based, This paper ex plores the supporting mechanism of this method as well as the numerical analysis results of Hongshigou Tunnel construction by using FLAC3D software. The application of the small-lead-tube advanced slip-casting method in the tunnel supporting is well justified.
