Abstract
The present paper deals with the response of pipelines subjected to liquefaction-induced permanent ground displacement and the subsequent failure of pipelines is discussed. Initially here, characteristics of permanent ground displacement are investigated based on model experiments. Next, formulae obtained by a beam theory are established and preliminary analysis is carried out in order to understand fundamental characteristics of continuous pipelines. Furthermore, response simulations are conducted for jointed pipelines by using a modified transfer matrix method. We present the influential factors determining the magnitude of the ground displacements and propose the method for evaluation of pipeline response to permanent ground displacement.
