摘要
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 geology conditions are very complicated at the entrance slope of No.3 tunnel,Bolai expressway that is the rock mass are broken and there are many creeps and landsides.According to the stability estimation of slope body and scheme demonstration we use the compact whole length sticky anchor post combined with grouting technology and extendod dischargc technique for the slope treatment.Thus,the self bearing capacity of slope rockmass is greatly increased and the rockmass retaining wall is formed accordingly.This provides the experience for the future similar slope treatment.
