| 摘 要： | 隧道施工受周边地质环境及隧道内部应力结构的影响极大。为保证隧道施工的进度和质量,隧道施工的监控量测显得尤为重要。本文以成渝客运专线新塘坊隧道为例,介绍了该工程监控量测的具体方法。通过对断面的监测数据进行比较和回归分析,得到了该隧道围岩变形的基本规律,确定了典型断面二次衬砌的合理施工作业时间,并得出了回归模型能够准确预报一周内变形的结论。

| Abstract: | Tunnel construction is strongly affected by the surrounding geological structure and the tunnel＇s internal stress.In order to ensure the progress and quality of tunnel construction,tunnel construction monitoring is particularly important.An on-site monitoring method of Xintangfang Tunnel in Chengdu to Chongqing High-speed Railway was introduced in this paper.Based on the monitoring data,the basic rule of rock deformation was found by regression analysis,and reasonable time for the second-time rock retaining was determined.The regression model used in this paper can accurately forecast the conclusion of deformation in a week. |
