| 中文摘要: |
| 基坑开挖对周边地表沉降的影响越来越受到重视。工程施工中如何保证基坑周边地表的稳定以及减小对周边环境的影响是当前研究热点和难点。本文以合肥市地铁一号线大连站深基坑工程为背景，介绍了工程概况和监测方案；对基坑围护结构内力、变形和周边土层沉降数据进行了对比；分析了基坑周边不同距离处与不同时间段内地表沉降的变化规律并对其原理进行了探究。结果表明：合理安排深基坑工程的施工进程与采取恰当的施工方法是保证安全生产的重要前提。本文可为相关类似深基坑工程的设计和施工提供一定的参考。 |

| The influence of foundation pit excavation on settlement of the surrounding ground has been paid more and more attention to. How to ensure the stability of surface around the foundation pit and reduce the impact on the surrounding environment in the construction have been hot topics and difficult points in the current research. This paper is based on foundation pit engineering of Dalian station of Hefei No.1 subway line as the background and introduces the general situation of the project and the monitoring program; then it compares datas in internal force and deformation of retaining structure of foundation pit, and the settlement data of surrounding soil,analyzes the change rule of ground settlement of surrounding foundation pit at different distances and different time segment and and probes into the basic principle.The results show that the reasonable arrangement of deep foundation pit engineering in the construction and taking the appropriate construction method are important prerequisites to ensure production safely. This paper can provide some reference of the design and construction for similar deep foundation pit engineering. |
