Abstract
There are numerous difficulties and risks in the construction of river-crossing tunnel of large-diameter metro. How to ensure the safety of the project and reduce the construction risk is the key issue requiring urgent solution. This paper, taking a project of constructing river-crossing tunnel of large-diameter metro as the research background, compared and selected the methods of constructing this river-crossing tunnel. Large-diameter slurry shield machine was recommended to conduct digging construction. Then, possible risks of the selected construction method were analyzed and summarized into two categories: risk concerning the project itself and environmental risk. Finally, corresponding measures to handle the risks were put forward.
