摘要
对巫奉高速公路某隧道进口边坡的工程地质条件进行勘察,并依此进行边坡稳定性分析。通过研究得出几种边坡加固措施,并由力学计算与分析得出以"注浆+锚索加固"为最优方案,可以使边坡稳定性系数提高至1.25以上。现场应用表明,"注浆+锚索加固"方案效果显著,可以为类似边坡加固工程提供参考。
Through analyzing the engineering conditions of expressway tunnel slope,the slope stability was studied and several reinforcement methods were put forward.Then,the method of grouting with anchor cable was determined as the best one based on mechanical calculation and analysis,which can make the stability coefficient arrive to 1.25 and more.The application result showed that this method was effective and can be referred to other similar slope reinforcement projects.
