Abstract :
    ABAQUS 6.10.1 finite element software has been used to model this study, and in order to study the behavior of pipelines parametrically, the parameters of pipe thickness, soil type, pipe diameter, and pipe burial depth have been analyzed as variables in the responses of buried pipes. have taken. So that the results are compared with each other and shown in the majority of the graph. The results of the research show that the stress increases with the increase in the diameter of the pipe and the stress decreases with the decrease in its thickness. In sandy soil, stresses have increased due to increased liquefaction in the soil. An increase in depth also causes an increase in weight and, as a result, a decrease in the liquefaction effect, and this can be seen well in the graphs.
