Purpose. The aim of the work is to analyze the existing domestic and foreign methods of strengthening the foundations of road bridges, taking into account the influence of various factors and operating conditions of these objects in the context of the problematic state of the transport and road complex. Methodology. The problematic issues of ensuring the smooth functioning of transport routes in modern conditions are highlighted. Complex measures aimed at restoring the operation of the transport infrastructure by promptly responding to existing and emerging threats of disabling transport routes as a result of military operations, sabotage, natural disasters, and man-made accidents have been identified. Findings. Generalization of modern foreign and domestic methods of strengthening the foundations of bridges made it possible to study the most effective, cost-effective and simple in technological design structures. Four directions of development of strengthening of foundations are proposed: 1) increasing the support area of shallow foundations on natural bases; 2) installation of additional pile foundations with their integration into a common structural system with existing foundations and the construction of additional supports; 3) strengthening the existing pile foundations by changing the bearing capacity of the foundations; 4) constructing other structural elements to ensure the reinforcement of the existing foundations of bridges. Originality. It consists in setting the task of strengthening the foundations of road bridges in the context of the problematic state of the transport and road complex. Practical value. Based on the results of the analysis, it is possible to recommend the most economically justified and quickly implemented methods of strengthening the foundations of bridges for making design decisions in the implementation of state programs for the construction and development of the transport and road complex of Ukraine and in modern world practice.
