Abstract:

Metro reconstruction is different from the construction of new line, which should guarantee the operation of metro. In order to study the solutions to the common problems encountered during reconstruction, the civil engineering and electromechanical problems encountered in the design of cooling tower, entrance and exit, and wind pavilion of Jihuayuan Station on GuangzhouFoshan Line are analyzed and researched; and the solutions are put forward. Meanwhile, the construction difficulties and key points as well as the operation management are analyzed. The results show that: (1)Nonstandardized design can be adopted in the reconstruction projects with limited surrounding conditions. (2)The parameters of nonstandardized design must meet the requirements of metro design before the reconstruction of the existing metro affiliated project. (3)According to the change of surrounding environment, the design and construction scheme must be implemented dynamically based on the opinions from experts, so as to make the reconstruction more humanized and economical.
