| 摘 要： | 通过模型试验分析浅埋大跨度洞室采用双侧壁导坑法施工中不同开挖阶段，不同开挖部位的地表沉陷表现，得出后开挖一侧洞室是引起整个洞室地表沉陷迅速增长的关键，为工程的安全施工提供了参考。

| Abstract: | Analysing ground surface subsidences measured from model test at different stages and locations of excavation with double side- heading method in shallow buried long span cavern construction, the paper points out that the excavating with one cave lagging behind will cause the whole ground surface of the cavern subsiding rapidly. This key point should be noted seriously during excavation, thus providing safety in construction. |
