| 中文摘要: |
| 结合浙江省上三线任胡岭隧道浅埋段，对明挖和暗挖和两种施工方案进行了详细的技术经济比较，针对复杂的地质条件，采用了挖孔桩系梁帷幕暗挖的施工方案并利用有限元方法对该方案进行了模拟分析，保证了施工的 顺利进行。实践证明，该方法是成功的、可行的、节省了投资，缩短了工期，为浅埋隧道的施工提供了一种新的方法。 |
| 英文摘要: |
| Together with shallow tunnel of Zhejiang Shangsan Road tunnel, the detailed technical and economical comparisons were made for the overcutting method and tunneling method. A tunneling method with the retaining structure of manmade hole pile whose tops is linked with a beam was used, and FEM was utilized so as to guarantee the safety of the engineering construction. It is demonstrated from the practical example that the construction method is not only available, but also saves a lot of project cost and reduces the period of the project. |
