| 摘 要： | 根据广元至巴中高速公路某隧道左线近水平沉积岩层周边收敛和拱顶下沉的观测数据,按照围岩级别和达到收敛位移总变形80%和90%的时间,通过对Ⅳ、Ⅴ级围岩段典型监测断面初期变形数据的数理统计和分析,得出了该隧道近水平沉积岩层围岩的变形特征和回归方程,并据此算出了与现场吻合程度较好的该隧道近水平沉积岩岩层隧道Ⅳ、Ⅴ级围岩总收敛的均值及满足二次衬砌要求的时间均值.最后介绍了位移加速度判据在评价该类隧道围岩稳定性和确定隧道二次衬砌施工时间的应用. |

| Abstract: | According to the data of horizontal constringency and arch sedimentation of certain left line tunnel in G-B high-way,in the light of surrounding rock classification and the percentage of total deformation time at 80% and 90%,the deformation features and regressive analysis of tunnel surrounding rocks were obtained and the tunnel lining time and average of rock deformation were obtained accordingly,which were closed to that of IV and V grades surrounding rock of approximate horizontal sedimentary rock after ... |
| Keywords: | New Austrian Tunneling Method(NATM) monitoring and measuring horizontal stratified rock tunnel surrounding rock deformation behavior regressive analysis |
