| Abstract: | The paper describes soil nailing bolting and shotcrete technology used on gravity retaining wall structure construction, thus two-way soil nailing bolted and shotcrete gravity retaining wall formed. To take foundation pit support engineering of a Beijing Olympic outdoor underground rainwater gathering tank as an example, explained its design philosophy, stability estimation and limit for the use in detail, especially expounded the method in retaining wall reinforcing design and construction in the round. The engineering practice has demonstrated that, the method has characteristics of reliable security, higher efficiency of construction and lower cost. |
