Numerical Evaluation of the Dynamic Response of Pipelines to Vibrations Induced by the Operation of a Pavement Breaker

摘要

This paper presents a two-and-a-half dimensional (2. 5D) coupled finite element-boundary element (FE-BE) method to predict r the response of lifelines subjected to ground -borne vibrations. The dynamic soil-structure interaction(SSI) problem is r solved with a subdomain formulation. The presented methodology is used to assess the risk of damage to a buried high pressure r steel natu -ral gas pipeline due the operation of a pavement breaker during the rehabilitation of concrete pave -ments. It is r observed that the stresses in the pipeline remain much lower than those induced by the operating internal pressure , which r indicates that there should be no fear of damage.
