Welcome, dear colleagues, and thank you for your interest!

The following collection includes my articles dedicated to the engineering-geological process of karst. From the beginning of my career as a geologist, I combined academic studies and scientific work at the university with practical experience in a surveying organization. This integration allowed me to reinforce my theoretical knowledge with practical skills and experience.

Karst is a hazardous process for industrial and civil construction. The most dangerous and least studied type of karst is covered karst. Unlike open karst, covered karst is not accessible for direct observation. In these articles, I describe my methodology that allows for the detection and localization of potential karst collapse areas. This methodology is applicable to localized sites, such as construction areas, in regions with covered karst.

The article discusses the possibility of assessing the hazard of karst sinkhole formation based on the analysis of the structure and composition of the strata of dispersed sediments that overlie soluble rocks in covered karst areas.

In conducting engineering-geological surveys, special attention should be given to hazardous geological processes that occur or may potentially develop in the study area. These processes, including karst phenomena, are addressed in Part II of SP 11-105-97 [3]. Section 5.2.7 of this document emphasizes the necessity of using, in addition to drilling and geophysical surveys, field testing of soils to "identify and delineate weakened and loosened zones within the overlying rock mass, determine soil properties, and study the relief of the roof of karst-prone rocks at depths accessible for probing." For these purposes, static probing is highly suitable and is one of the main and most widespread types of field tests in Russia...

As is known, hazardous geological processes, including karst processes, pose significant challenges both during the economic development of territories and during the operation of structures. Karst processes are particularly dangerous for settlements and linear structures in the European part of Russia, as this region is densely developed and populated.

In this report the author aims to examine some aspects of formation conditions of the karst area of Dzerzhinsk CHPP (combined heat and power plant) in Nizhny Novgorod region. Structural analysis of paleotopographies is used for this purpose. The corresponding method of prediction of a sinkhole formation is briefly illuminated...

The basic genetic types of collapse sinks caused by covered karst development and man-made activity are considered in the paper. A brief description of the signs preceding these collapse sinks formation is also given and the possibility of their discovery by site investigations is estimated.

Geoecology, among other things, involves the study of the natural environment and its interaction with human economic activities, as well as the factors that influence this relationship. One of the most significant of these factors is hazardous geological processes, with karst being one of the most prominent.

In this article, the author gives a description of an experiment performed by physical modeling of the «karst cavity – overburden soil» system, followed by an imitation of the collapse of the cavity roof and the formation of weakened zone over it.

In covered karst conditions, the main problem in assessing the karst hazard of a territory is the fact that karstified rocks are hidden from direct observation.

In covered karst areas, there are precursory signs of a preparing sinkhole formation. These signs are features of the overburden structure. In particular, they include suffosion decompaction zones of noncohesive soils over fissures and cavities in soluble rocks. The existence of such zones in a geological cross-section can be considered as a precursor of a karst-piping sinkhole formation. This paper presents a detailed description of this phenomenon studied using a laboratory physical modeling and in the natural conditions. The authors consider the principles of search and identification of suffosion decompaction zones on the basis of analyzing the spatial distribution of granulometric composition parameters of noncohesive soils in the lower part of the overburden.

Ensuring trouble-free operation of industrial, civil and other types of construction projects built on karst-prone territories is one of the most important technical tasks of our time. The article describes the principles of rational choice of methods for engineering protection of construction objects located on karst-hazardous areas, where signs of sinkhole formation preparation were found during engineering and geological surveys. These signs are: buried sinkholes; zones of suffosional deconsolidation of cohesionless soils covering soluble rocks; zones of weakening of disperse soils over karst cavities, and also the presence of non-colmated cavities in soluble rocks. Expediency and efficiency of different kinds of anti-karst protection technics, put into Russian and foreign practice in these settings, are considered in succession. It is noted that it is necessary to take into account the signs of karst sinkhole preparation when prescribing anti-karst measures. The practical significance of such accounting is that it makes it possible to avoid serious engineering errors that are sometimes made during the design or implementation of anti-karst protection.
