Abstract When urban shield tunnels cross over existing pipelines, such crossing will have an impact on the pipe? lines. This paper reviews the status quo of the research in the impact of shield tunnel crossing on existing pipelines in terms of the following four aspects: theoretical equation, simulation calculation, model test and on-site measurement. Firstly, in theoretical study, three types of pipeline models were mainly compared and analyzed on the basis of soil deformation, and the method for selecting key parameters was discussed in detail. Secondly, although simulation and model test had direct advantages in the study on parameters related to the interaction between pipelines and ground, and what the study focused on had been changed from univariable coupling to multivariable coupling, the rationality of study results still relied to a large extent on the selection of constitutive model and test equipment. Lastly, as for pipeline deformation measurement, the initial analysis was conducted for the similarities and differences of two tunnel crossing methods. Besides, this paper also introduces the "sheltering effect" of the adjacent existing structures and the impact of pipeline joints on the predicted results, and summarizes control indicators and preventive measures from the aspect of flexible pipes and rigid pipes. Among the passive protection measures, grouting for reinforcement is the most widely used one.
