| 摘 要： | 介绍了采用土钉墙支护的一典型深基坑工程施工监测与过程。通过对监测数据的分析。支护方案得到了调整，限制了位移的进一步发展，使得基坑施工顺利进行。根据对土钉墙变形特点的分析，揭示了土钉墙平移破坏的本质，并结合极限稳定性验算分析，探讨了其稳定性和破坏机理。

| Abstract: | This paper introduces field observations of a typical case of soil nailed wall in basement excavation in Wuhan city. By analyzing monitoring data, the original profile of earth - retaining structure is modified in order to restrain the further movements. After that, the excavation goes smoothly. According to the displacement curves recorded during excavation, the potential slippage mechanism of this soil - nailed wall is found to be translational. Its overall stability is evaluated using limit analysis method. |

| Keywords: | soil nailed wall information construction method monitoring stability translational failure mechanism |
