Abstract:

Qingnian Avenue Station of Shenyang Metro, which is located in fine silty sands, crosses underneath sewage pipelines with short distances. Taking the construction of Qingnian Avenue Station as example, the author presents such measures as the surface treatment of the utility pipelines, the control of the construction settlement and the advance ground consolidation that are taken during construction in order to protect the utility pipelines and to guarantee the construction safety .The paper can provide reference for similar works in the future.
