Abstract: The damage of buried pipeline is controlled by site condition, such as faults, characteristics of rock and soil. Analyzing the influence of site condition on the damage of buried pipeline under earthquake load is the key of earthquake lifeline engineering. By the operation of defintion body in ADINA, the type of site body is selected, and pipeline body is subtracted from site body by Boolean Body Operators. Therefore, the geometry model is obtained. Through model preferences, parameters of the model are defined, such as the characteristics of rock and soil in site, characteristics of pipeline and faults. Time function of earthquake load and displacement load of faults are applied, initial displacements are defined based on the movement of faults, and pipe-soil friction is considered by contact control in ADINA. According to the calculating results, influence of buried depth, parameters of faults, pipe-soil friction, and faults movement is investigated. Some advice for the protection of buried pipeline under earthquake load is proposed.

Key words: Site, buried pipeline, faults, ADINA, pipe-soil friction
