Abstract: This paper presents a case history of influence of deep excavation on the adjacent utilities with embedment depths. The cut-and-cover method was used in the Zaozhuang Station of Zhengzhou Transit Project No. 8 Line and the effect of deep excavation on the adjacent pipelines with various embedment depths. The results showed that the deep excavation of the subway station has influence on the deformation of pipeline, and the pipeline with deeper embedment depth is less affected. With the increasing of excavation time, the influence on pipeline will gradually decrease.

Key words: deep excavation, underground pipeline, pipeline embedment depth
