Reducing impact of embankment soils on shore support of bridge on the approaches to bridges

Abstract

The article defines the reduction of active ground pressure and amplitude-frequency characteristics by theoretical and practical studies on approaches to bridges by driving reinforced concrete piles into the embankment. Reinforced concrete piles were driven into the model of the roadbed, and vibrations were created using a vibrator mounted on piles. The frequency of these oscillations was 50 Hz, and the values of the oscillations were recorded at different points of the roadbed. Processing the obtained results made it possible to determine the distance between piles for different soils on the transition section reinforced with reinforced concrete piles. As a result, some of the vibrations in the roadbed are transmitted to the base using reinforced concrete piles. The amplitude-frequency characteristics (frequency response) of the vibrations of the embankment soils are decreasing.
