Digital models of the artificial structures for monitoring and forecasting safe operation in the cryolithic zone

Issues related to the operation of artificial structures in the northern construction and climatic zone, which covers 40 percent of the territory of the Russian Federation and 80 percent of the territory of the Russian Far East are important in all aspects. At the same time, we are talking not only about existing artificial structures of the transport infrastructure, but also about objects under construction, as well as about objects planned for construction. For example, in the territory under the jurisdiction of the Far Eastern Railway, there is 1 object per 1 km of track belonging to small artificial structures, these objects are located in the cryolithic zone, which imposes additional requirements for monitoring the technical condition and carrying out additional measures aimed at preventing the transition of the object's structures to an emergency state. The currently existing methods of monitoring the technical condition make it possible to control and predict with a high degree of reliability possible conditions, causes and consequences of incidents, however, taking into account the growth of the possibility of digital modeling, visualization and forecasting, it is advisable to use all available possibilities for the formation of digital models of artificial structures objects, for the most effective preservation of their working condition.

The article reviews an example of numerical modeling and digital simulation of base and foundation of artificial structures, given a solution of the numerical task of thermal fields distribution, also solved a numerical task with a forecasting of changes in the time perspective. The purpose of this research was assessment of possible negative events at various stages of the artificial structure’s life cycle and establishing a digital model for the forecasting safe operations.

As a result, a digital model of foundations was obtained, which can be used to solve various tasks.
