Abstract Nanjing Heyan Road cross-river tunnel is constructed with a super-large-diameter slurry shield (excavation diameter 15.07 m)，which needs to pass through the Nanjing Baguazhou embankment. With this project as the background，the finite element analysis software is employed to establish a three-dimensional numerical model of the super-large shield tunnel crossing the Yangtze River embankment. Taking into account construction factors such as soil excavation，slurry support，segment lining，grouting behind the lining，and ground loss，a detailed numerical simulation of the construction process is carried out. The numerical solution is compared with the monitoring data to verify the rationality of the model，and then to study the variation of the embankment settlement when the slurry shield passes through the embankment，and analyze the influence of different grouting pressures on the embankment settlement. At last，this paper summarizes the settlement control measures of the slurry shield passing through the embankment from seven aspects. The measured maximum settlement of the embankment is 21.7 mm，which is controlled within 0.5% of the height of the embankment，and a good control effect has been achieved，which can provide a reference for similar projects.

Key words： tunnelling engineering super-large-diameter shield crossing the embankment settlement law numerical simulation control measures
