Research conclusions: The pile and beam underpinning protection scheme and tracing grouting protection scheme were presented to overcome the problems of the deformation and settlement of the pipeline caused by shield machine under －passing the pipeline． The introduction was given to the advantages and disadvantages of these two schemes． The tracing grouting scheme was chosen． Although，with the tracking grouting scheme，the deformation of the pipeline was not controlled accurately，but the deformation was controlled to the allowable range． In addition，the tracing grouting scheme had the features of using smaller grouting device，occupation of less land，easy operation，low cost and being available for control of the pipeline settlement． Finally，the safety of the pipeline was ensured by adopting this scheme while the tunneling of the shield machine was strictly controlled with the synchronous grouting and informatization construction．The project can provide the reference to the similar works．
