复合地层盾构隧道工程地质勘察方法的研究

Study on Geological Investigation Methods for Shield Tunneling in Mixed Ground

盾构法施工与其它地下工程施工方法相比有其特殊性,反映在相应的地质勘察工作中就会有专门的要求,结合复合地层中盾构施工的特点,对目前的勘察内容、工作量等提出了改进意见,对地质勘察阶段的划分提出了看法。

Compared to the construction methods of the other underground works, the shield tunneling method has its own special features, therefore the geological investigation for the shield tunneling works also has its own special requirements. On basis of the features of the shield tunneling in mixed ground, the authors make some recommendations on the content/quantity optimization and stage division of the geological investigation works in the paper.
