摘要

对于隧道塌方地段，选取合适的施工方案是关键问题。结合乌竹岭隧道塌方工程实际条件，采用非线性有限元方法对两种施工方案进行模拟分析。计算结果表明，双侧壁导坑施工方案相对于上弧形导坑施工方案，能够更好地控制围岩位移、改善其受力状况、减小初期支护受力，且围岩破坏区范围较小，可见双侧壁导坑施工方案更适合于隧道塌方段的施工。通过现场监控量测分析，隧道断面净空收敛变形和拱顶下沉稳定速度较快，最终变形值较小，隧道主体稳固，没有任何变形，说明所选处治方案对抑制隧道塌方段效果良好

Abstract

At the region of tunnel collapse

it is important to select appropriate construction scheme. Based on the engineering condition of tunnel collapse in Wuzhuling

two different construction schemes are simulated by the nonlinear finite element method. Compared with annular drift method

double-side-drift method can better control the displacements of surrounding rock

improve the force status of surrounding rock

decrease the force of primary support and make the range of plastic zone smaller. Therefore

double-side-drift method is more suitable for tunnel collapse treatment. Then

the analysis of site monitoring measurement shows that convergence displacement and vault crown settlement tend to stable condition quickly and the deformation value is smaller. The subject of tunnel is in stable state and has no deformation. It is shown that the treatment effect of double-side-drift method which is selected to through tunnel collapse is significant.
