摘要: 分析了隧道山体蠕滑病害工点病害原因,结合工程实际情况,提出采用微型桩群对病害进行加固治理,在控制山体滑移的同时,结合引排地下水、地表注浆等措施进行病害处治。病害体加固前后的模拟分析及现场监测均表明,边坡未加固前处于蠕滑阶段,采用微型桩加固后效果明显,位移明显收敛。相关病害治理措施,可为类似工程病害治理提供参考借鉴。

Abstract: The creeping hazards of mountain tunnels are reviewed in this paper. The micropile was used as rehabilitation method based on the project need with the combination of diverting the groundwater, and grouting around the tunnel. Both the numerical analysis and the construction monitoring results indicates that the micropile rehabilitation was effective and the creeping movement of the tunnel has converged.
