The article deals with the transverse vibrations of a single-span beam bridge whose pile section interacts with the surrounding ground under moving load. It is assumed that the deformation of the structure does not exceed the elastic limit and the vibrations are linear. Problems are solved by analytical Fourier method in given boundary conditions. The results are given in the form of stress and deflection distributions over time and bridge structure lengths, and their analysis is also presented.

В статье рассмотрены поперечные колебания однопролетного балочного моста, свайная часть которого взаимодействует с окружающим грунтом при подвижной нагрузке. Принято, что деформация конструкции не выходит за предел упругости и колебания носят линейный характер. Задачи решены аналитическим методом Фурье в приведенных граничных условиях. Полученные результаты представлены в виде распределения напряжений и прогибов по времени и длине мостовых сооружений, а также проведен их анализ.
