摘要
Abstract
Based on the Nanning subway Line 1 , the station of Shibu is designed to pass underneath Shibu river and its bridge foundation. Due to the constraint of engineering conditions, the cut-and-cover method is adopted to resolve three design problems including river diversion, foundation ditch support and re-construction of bridges. According to the in-situ circumstances, the correlation between the three is analyzed, and an integrated design scheme is proposed, which is composed of cofferdam plus diversion by draft tube, anchor cable plus internal support system and construction of bridges with box girder. Subsequently, the specific design approach is introduced and the main points of design for each item are put forward. The construction of the metro station and re-construction of bridges are successfully implemented due to the application of this design scheme and the designed flood carrying capacity is guaranteed, which demonstrates the rationality and feasibility of the scheme.关键词
