The stability of a pipeline section located on an elastic foundation, rigidly fixed at one end, and having an elastic inertial support connected to the foundation at the other end is investigated. By using the dynamic method, the influence of various pipeline fixing parameters, such as the elastic foundation stiffness, and the stiffness and mass of the additional support on the pipeline stability is analyzed. The stability domain boundaries are constructed on the plane of parameters characterizing the velocity and mass per unit length of the flowing liquid.
