Study on programming of subway station construction site based on dynamic site layout planning

The construction site of urban subway is narrow and takes up a long time. The dynamic adjustment of the site in the construction process can effectively save land resources. In order to avoid the malpractice of the construction site dynamic adjustment only by experience arrangement, a DSLP dynamic site layout planning was proposed. Based on the traditional SLP system layout method, this method divided the construction stages and determined the movable type of the site. According to the comprehensive relationship between different operation areas in each stage, schemes were designed and evaluated according to the material handling cost, construction management intensity and secondary handling index, so as to determine the relative optimal scheme in each stage. Finally, the scheme in each stage were connected in series to form the dynamic planning layout of the whole construction process. The method and evaluation system were applied to Chaoyang village station of Changsha rail transit line 6, which greatly reduced the construction area and provided effective guidance for site layout. © 2020, Central South University Press.
