Earthquake Resistance Measures Research On Pipelines Across Fault

With the development of economy, buried pipelines has been widely used. Buriedpipelines have become a very important part of industry and our living. Therefore it isnecessary to analyze the earthquake resistance measures of buried pipelines to large faultmovements and evaluate the anti-earthquake capability of buried pipelines. It will offer abasis for the design, reinforce and reconstruct of buried pipelines.At first, many previous theories for the response of buried pipelines crossing fault arereviewed, a lot of main factors are collected. While reviewing the main earthquake resistantmeasures’ advantages and disadvantages of the pipe across fault, the writer proposes onemeasure for the same purpose.Secondly, established the pipeline model by finite element analysis software, thethree-dimensional finite element model of the buried pipeline under the fault was established.The pipelines adopts4node shell element.The spring and damper adopts the non-linearequivalent spring element.Thirdly, some parameters influencing seismic response are analyzed through practicalcalculation examples. For example spring stiffness,damping coefficient, diameter, thickness,angle and so on. Some useful conclusions are drawn.Finally，seismic effect analysis has been introduced. From analysis of result, seismiceffect is good.
