| Abstract: | The geologic condition for a river-crossing tunnel engineering was very complex and the construction environment was bad,so the demand of wall rock supporting was particularly high.In order to ensure the supporting effect,the steel grille support technology was improved,and grille-channel steel concrete support technology was formed.The design and construction of the supporting technology is introduced,and the dynamic mechanism is analyzed by numerical simulation,to verify the safety and stability of the technology theoretically. |
