Differential equations and appropriate boundary and initial conditions of Г-shaped pipelines are derived on the basis of Hamilton-Ostrogradskiy variation principle. Derived system of equations is solved by Finite Difference Method of the second order of accuracy. The program is formed on the basis of the algorithm of computer realization in oriented Delphi 7. Results of solution of dynamic problems of underground Г-shaped pipelines are presented in the form of graphs.
