Fiber Reinforced Plastic Mortar pipes（FRPM pipes） have been widely used in civil and hydraulic engineering.The current seismic analysis models for buried pipes generally ignore the dynamic interaction between pipe and surrounding soil

and most of the models are for homogeneous pipe.For the above-mentioned reasons

the current seismic analysis models for buried pipes cannot be applied to FRPM pipes with laminated structure.The whole seismic analysis model for buried FRPM pipes is presented.The model takes the laminated structure of FRPM pipes into consideration

and the complicated dynamic interaction between pipe and surrounding soil and the propagation of seismic scattering waves from finite field to infinite field are also considered in the presented model.The analysis results of an engineering example show that the proposed model in the paper can rational analyzed the dynamic response of buried FRPM pipe under seismic loading.
