摘要：As part of the study, a field experiment was conducted, the results of which were used to evaluate the dynamic effects of vehicles on the elements of bridge structures due to deformations of the approach slabs. Drawdowns of the pavement at the interfaces of artificial structures with approaching embankments lead to the development of additional dynamic transport impacts, which give them accelerations reaching 1.8 m/s2 (for the studied objects). Taking into account a detailed survey of the places of interfacing bridges with approaching embankments, there has been proposed a method for eliminating the causes and consequences of the deflection of approaching slabs without disassembling existing structures. The method is based on the injection way of filling voids and fixing soils. A method of eliminating the causes and effects of deflection of approaching slabs without disassembling existing structures, based on the injection method of filling voids and fixing soils, ensuring evenness on the site by milling the coating with the laying of the leveling layer.
