Transport of dangerous goods by rail, and threats to the subsoil of the railway surface in the event of a disaster
Abstract
In Poland, in 2020, the mass of dangerous goods (loads) transported by rail was 26 151.06 thousand tone. This translated into the performance of 8 899 691.89 thousand tone - km of transport performance. In 2020, these figures accounted for 11.72% of the weight of goods transported by rail. The situation is similar in other countries around the world. With such a large volume of transport of dangerous goods by rail, there is a high risk of a railway disaster involving hazardous materials. The effects of such a catastrophe affect the ground surface of the railway track and groundwater. For modeling, generalized dynamical systems are used. These are mathematical models of real systems describing the relationships between the so-called input ⃗ and output (response) of a dynamical system. In the case of the railway disasters discussed here, they determine the functions showing the way the effects of the disaster spread in the subsoil of the railway track and show the properties of these functions. For this modeling, a non-classical calculus of operators is used that generates generalized dynamical systems, as the phenomenon of spreading the effects of a catastrophe in the ground is a complex dynamic process. It can be either slow or abrupt. This has been taken into account in the process analysis. It has been shown that the occurrence of a disaster, including the one involving hazardous materials, is influenced by the reliability of the railway line and its components, as well as the reliability of the subsoil. It was indicated that the effects of a disaster involving hazardous materials affect the discussed reliability. Determining the function of unreliability, reliability and intensity of damage to the subsoil is helpful in determining the methods of restoring the subsoil to its original (initial) operating parameters.
