| Abstract: | All kinds of optional excavation methods highway tunnel with small interval were summarized and compared with respect to their advantages, disadvantages and applicability, and then, the construction method of the support project of Daoguanshan Tunnel and the distance request between the advancing drifts were presented. Next, the strength- erring technique for the shared surrounding rock of Daoguanshan Tunnel was proposed, on the base of the analysis for characteristics and applicability of all strengthening methods of the shared surrounding rock of tunnel with small interval, which include the pipe grouting, prestressed bolts, parcel lengthening systemic bolts, increasing systemic bolts, deep grouting from ground surface, etc. |
