| Abstract: | On the basis of mechanics theory of special large-span shell structure, a new type of shell shotcrete was studied and designed. It can improve the bend resistance of the shotcrete, and make the shell shotcrete structural compressibility. The new structure has an ability to sustain the great soil pressure and dynamic force. The practical test in the soft rock tunnel indicate that the new structure can economize on materials and play an important part in yield and supporting capacity. |
| Keywords: | shell structure soft rock tunnel shell shotcrete internal force analysis |
