| 摘 要： | 针对基坑开挖过程中对下方运营地铁隧道的保护问题,通过基于工程实测的隧道回弹隆起值的监控,对隧道回弹隆起的规律进行了分析研究。在考虑基坑开挖时空效应的基础上,分别对基坑放置时间、开挖方式、分块开挖宽度对隧道回弹变形的影响进行了分析和归纳,得出了隧道位移受基坑放置时间、开挖方式、分块开挖土体宽度的影响的规律。

| Abstract: | Around the protection of the underneath operational metro tunnel from foundation excavation,it analyzes the regulation of tunnel upheaval through monitoring the measured tunnel upheaval values.Considering the excavation time-space effect,analysis is made to tunnel rebound deformation from the aspects of excavation retention time,excavation method and width.And it comes to the regulation of tunnel displacement which is influenced by excavation retention time,excavation method and width. |
