Internationa Analysis Between Buried Pipelines Crossing Fault And Soil

With the development of national economy,buried pipelines has been widely used as thetransportation of gas and liquid.It work properly or not is directly related to modern industrialproduction and the normal life of the residents When earthquake comes,one of the mainreasons about buried pipelines across the fault damage is fault rupture.Based on this situation，it is essential to make research on interaction analysis between buried pipelines crossing faultand soil.Firstly,This article first chapter state the topic selection background and significance inthis paper, list the analysis research about buried pipeline crossing at home and abroad,thedestruction mechanism and main factor of buried pipelines crossing fault is analyzed,meanwhile the problem of buried pipelines crossing fault to be solved in the paper.Secondly,Finite software ADINA is used to make the mechanics analysis model of buriedpipelines crossing fault into come true,numerical simulations are completed by setting thebirth and death of unit,the new soil spring buried pipelines model is established, at the sametime compare the results of single pressure soil spring buried pipelines model with tensionand compression soil spring model,compare the results of single pressure soil spring buriedpipelines model with solid soil model too.Lastly,make buried pipelines research analysis about some influence parameter such asdiameter,thickness,depth,bury ground,fault offset and so on.
