| 摘 要： | 介绍了广巴高速公路某近水平岩层隧道新奥法施工过程中现场监测的项目、手段及方法,基于监测结果,分析了近水平岩层隧道围岩变形特点、变形原因,划分了围岩变形阶段。以隧道左线进口段某断面为例进行回归分析,利用位移加速度正负的判据分析评价围岩稳定性。相关监测及分析结果为采取整治措施和后续施工提供科学依据,也为日后分析研究提供参考。

| Abstract: | The techniques and methods used in in-situ monitoring of surrounding rock deformation of approximate horizontal rock tunnel construction in G-B high-way project are presented.Based on the measured data,the deformation properties and deformation causes of surrounding rocks were analyzed and the classification of the deformation stages was discussed.The regression analysis for surrounding rock deformation was implemented on certain section of the tunnel.And the stability of surrounding rocks was also evaluated using displacement acceleration analysis.The monitoring and analysis results provide the scientific basis for high-way tunnel construction. |
