Lanzhou Metro Line 1 is the first Metro Line in Gansu Province. Before the construction of buildings along the line, it is necessary to analyze the safety of the subway tunnel to ensure the safe operation of the subway. The new project, No.23 and No.24 plots of the old plant reconstruction project of Lanshi group (Lanshi ⋅ hobska n District), is close to the Shizi tunnel between the west railway station and the West Railway Station of Lanzhou Urban Rail Transit Line 1 phase I project, The excavation and supporting construction of foundation pit may have an impact on the structural safety of Shizi tunnel between West Railway Station and West Railway Station in the first phase of Rail Transit Line 1. It is particularly important to analyze and study the structural safety of subway tunnel before the construction of this project.
