跨活动断层埋地管道抗震研究进展
Research Progress on Seismic Resistance of Buried Pipelines Crossing Active Faults
摘要
Abstract
This paper introduces the types,characteristics,and failure mechanism of active faults,and summarizes the research progress on seismic resistance of buried pipelines crossing active faults at home and a-broad from three aspects of theoretical research,experimental research,and numerical simulation.This paper introduces the main methods currently used in theoretical research,named the Newmark hall method and Ken-nedy method,as well as their improved versions.The numerical simulation research utilizes model types such as beam element model,shell element model,solid element model,and soil spring model,as well as the mechani-cal response law of pipeline obtained through simulation;At present,the main experimental methods used by scholars for experimental research and the key conclusions regarding pipeline seismic resistance;and the new methods proposed by scholars in the field of pipeline seismic resistance.Finally,based on the research results of scholars on seismic resistance of buried pipelines crossing active faults,the deficiencies existing of seismic re-sistance of pipelines crossing active faults are discussed.Suggestions are put forward that special attention should be paid to the combined effect of fault dislocation and seismic wave on pipelines,the fatigue damage of pipelines under long-term seismic action,and the improvement of the accuracy of pipeline model under large de-formation conditions,providing a reference for the future development direction.关键词
