博莱高速公路 3#隧道进口边坡工程地质条件复杂 ,岩体破碎 ,开挖过程中发生过多处滑塌。基于坡体的稳定性计算及方案论证 ,边坡治理通过密集的全长粘结锚杆并结合灌浆工艺及疏排水技术 ,大大提高了边坡岩体的自承载能力 ,成功地形成了岩体挡墙 ,为今后类似的边坡治理提供了借鉴。
The engineering geological conditions of 3 # tunnel entrance slope on Bolai Expressway are complex, the rock mass is broken and there are many landslides in the excavation process. Based on the calculation of slope stability and the feasibility of the scheme, the slope treatment greatly enhanced the self-bearing capacity of slope rock mass by means of dense full-length bonded anchor combined with grouting technology and drainage drainage technology, and successfully formed the rock mass Retaining wall provides a reference for similar slope treatment in the future.
