Bridges, Emperor Alexander I St. Petersburg State Transport UniversityThis research presents a study of the dynamic impact of high-speed trains moving on continuous and discontinuous span bridges. As an example of this study, a continuous span ballast bridge project with a total length of 174 m has been adopted, according to the scheme 27+ 3 × 40+ 27 m, allows us to analyze the dynamic impact of displacement of different trains at a speed range of 100km / h to a maximum speed of 300km / h, as well as to make a comparison of the dynamic behavior of this continuous-span HSR bridge from the discontinuous span bridge systems with lengths of 27m and 40m, and draw conclusions about the dependence of the maximum dynamic coefficients and the vertical accelerations at the midpoints of the span bridges as a function of the moving speed of the deferent trains. The resolution of the dynamic problem of moving loads during design and calculation is based on the modeling of the Bridge-Train system by the complex program, realized by the finite element method (FEM). In this work, for the numerical simulation of dynamic problems, Sofistik software was used. The results show that the increase of train speed up to 300 km / h, it is possible to manifest resonant vibration modes of the structures in span.
