| Abstract: | According to some problems in Daoxi tunnel, that is the shallow burial depth of exit section with bias, broken surrounding rocks, the developmental joint fissure, and the bad self-stability capacity etc. , the paper intensifies the shallow buried section of the tunnel by using the surface pre-grouting design, illustrates the construction craft for the grouting and the precautions, and proves the arch stability condition for softweak surrounding rock. |

| Keywords: | surface pre-grouting shallow burial of cave mouth soft-weak surrounding rock tunnel design |
