Hydrogeological processes and phenomena and assessment of their danger

Abstract

In modern complex engineering-geological conditions of cities, the growth and scale of development of dangerous natural processes and phenomena can be traced. In many ways, the reasons for this are not only technogenic load on the soil, but also changes in climatic factors. Buildings and objects exposed to hazardous factors of hydrogeological processes are becoming increasingly vulnerable to their impact, which can lead to catastrophic consequences. One of the main conditions for increasing the stability of objects is the adaptation of existing methods or approaches to assessing natural hazards that have a negative impact on the physical state of such objects. The authors of the article propose an adaptation of the international INFORM approach in order to assess the hazard level of natural processes and phenomena in built-up areas. The task is also to develop a methodology for assessing the physical state of objects exposed to such processes and phenomena. To solve this problem, the study examines the practical aspects of applying the principles of the Weber-Fechner law in determining the state of the structural parameters of buildings that are under the influence of negative factors of hazardous natural processes and phenomena. The study is based on the principle of changing the category of the physical state of objects from changes in the level of exposure to hazardous factors of natural processes and phenomena.
