| 摘 要： | 隧道洞口段选址在滑坡体上的现象较为常见。以玉园隧道为工程实例,阐述了隧道洞口段滑坡地质灾害的成因及防治方法,通过数值计算针对性地提出该滑坡的应急处治措施。计算结果表明现有变形体为牵引式变形,卸载方案不利于其稳定,进而提出抗滑桩+降水、抗滑桩+旋喷桩2种方案,探讨2种处治方案的比较与选择,为类似的工程提供经验。

| Abstract: | It is common that the tunnel portal site sits on landslide mass. Taking the Yuyuan Tunnel as an engineering example, this paper expounds the cause and prevention measures, and analysis method of landslide hazard in tunnel portal, and puts forward the emergency treatment of the landslide by numerical calculation. The calculation results show that the present deformation body is tractive deformation, and the unloading scheme is damaging to its stability. Thus, it puts forward and compares 2 kinds of schemes of anti-slide pile + precipitation, anti-slide pile + jet grouting pile, thus to provide reference for similar projects. |
