Consideration of the environmental impact on the seismic inertial forces of the railway track in difficult conditions.

The article is written on the basis of full-scale and experimental studies, and from a theoretical point of view, it is justified to reduce the impact of vibrations resulting from an earthquake and high-speed train traffic on the railway trackbed and bridge supports. As a result of field and model experiments, an active seismic-insulating coefficient of seismic load was determined, affecting the roadbed of railways and bridge structures in different ground conditions. An expression defining the distance between driven reinforced concrete piles to strengthen the roadbed has been developed, taking into account the obtained active seismic insulating coefficient. Reduction of seismic and vibrodynamic forces affecting the roadbed and bridge supports, taking into account the active seismic isolation of the seismic load of soils, the acceptance of the distance between reinforced concrete piles equal to 15 m in weak soils, is experimentally determined and theoretically justified.
