Abstract:In view of the complicated construction conditions in the Comprehensive Upgrading and Reconstruction Project of Lanzhou White Pagoda Mountain, in order to analyze and solve many control difficulties in the project and make the project proceed smoothly while ensuring safety. Through four aspects: route selection, geological disaster assessment, ancient building protection, and traffic impact assessment, four major control difficulties affecting the feasibility of the project are analyzed, and corresponding solutions are proposed. Propose the following plans according to local conditions: the road is changed to a tunnel through which passes through White Pagoda Mountain to improve the transportation capacity of the local road network, install anchor cable anti-slide pile, anchor cable frame and retaining wall structure at the exit of the tunnel to prevent landslides, the tunnel construction method adopts fully mechanical excavation to reduce the impact on the ancient buildings above White Pagoda Mountain, and the design uses prefabricated bridge piers and steel box girder structures to shorten the on-site construction period and reduce the adverse impact on local road network traffic during the construction period.
