| 摘 要： | 某隧道是一座分离式浅埋隧道,进口段存在偏压现象.在隧道修建过程中相继出现边坡滑移、二衬开裂掉块等病害.为分析病害原因,对洞内变形、二衬表面应变、临时支撑应力及边坡表层、深部滑移等项目进行了系统的监测.监测数据显示洞内变形基本稳定、边坡滑移发生在浅层.结合现场调查,认为二衬开裂掉块的主要原因是混凝土施工质量缺陷,而边坡表...

| Abstract: | A separate-type shallow tunnel bears unsymmetrical loading in the entrance region.In the process of the construction,it happened slope slipping and secondary lining cracking successively.In order to reveal the reasons,system monitoring items were executed aiming at the deformation of the tunnel contour,the surface strain of the secondary lining,the forces of the temporary support frame and displacements on the surface of and inside the slope.The monitoring data showed that there were no obvious deformation ... |
