The objective of this article is to consider the use of predictive mathematical models for assessing risks associated with a critical loss of values of functional quality of bearing structural elements (foundations) of bridge structures using methods of probabilistic analysis and forecasting the risks of reducing of values of indicators of the technical state of structural elements. The research results in development of an algorithm and a mathematical model that characterise the features of the process of reducing of values of indicators of the technical condition of load-bearing structures during the service life cycle. The results of assessing the loss of functional quality of foundations obtained using this model are presented. The practical significance of the study relates to the possibility and expediency of using probabilistic methods for predictive assessment of the technical state of loadbearing structures. With the help of an appropriate mathematical model, it becomes possible to proceed with design rationale of indicators of functional quality of foundations of bridge structures. The need to improve regulatory provisions for design and forecasting of indicators of the technical condition of transport infrastructure objects is substantiated.
