In view of the similarity relation selection problem of structures and soil in present underground structures shaking table test

taking a long-distance buried pipeline as a research object

according to the structural dynamics theory and the similarity theory

and using dimensional analysis method

we establish the dynamic similarity relation and design the model similitude relations.Then

the seismic performance of some long-distance buried pipeline

including the prototype and different similitude relations of pipe-soil model

is studied with numerical test.We analyze the dynamic effect of different pipe-soil models

and deduce the prototype response by the results of the model according to the similitude relations

and compare with the prototype calculating value

and then study the model and the prototype similarity relation deeply.Finally

the reasonable similarity relations of the shaking table test are proposed

which will be a foundation for the upcoming shaking table test of long-distance buried pipelines.
