隧道洞口段滑坡体处治技术研究

摘要

The exit section of BaiLongAn tunnel is in the landslide,it use the anchor frame beam and anti-slide pile to treat the landslide,and use numerical software Midas to conduct three-dimensional numerical simulation of tunnel excavation.The result show that mountain and tunnel lining、anti-slide pile so are all safe,and show good results of treatment,it have a certain significance for similar projects.%白龙庵隧道出口段处在滑坡体中，采用了锚索框架梁及抗滑桩对滑坡体进行处治，并用 Midas数值计算软件对隧道开挖进行三维数值模拟，结果显示山体和隧道衬砌、抗滑桩等都是安全的，表明处治效果良好，对类似工程有一定的借鉴意义。
