Hydrogelological Peculiarities of Calculation of Scarps and Slopes Stability Within Urbanized Territories

Abstract

The article considers the issue of groundwater influence on scarps and slopes stability. The relevance of the study is caused by the tendency to increase the frequency of appearance of exogenous geological processes due to technogenic impact. Timely detection of hazardous areas and application of measures to prevent the development of landslide processes will avoid significant damages. An important factor that directly affects forecasting is a reliable calculation of the stability and an adequate interpretation of the results, depending on the choice of the calculation method. Different methods of calculation, different complexity of their implementation and uncertainty of the results aggravate the problem, especially with regard to groundwater levels fluctuations and their further influence on sustainability parameters. The existing methods for calculating scarps and slopes stability, in particular taking into account temporary changes of groundwater levels, are analyzed. This study proves that the further increase in the reliability and accuracy of the results of calculations primarily depends on the improvement of methods for determining the water-physical state of soils and hydrodynamic features of groundwater movement. The authors provide evidence of the necessity to take into account intensity value of infiltration recharge at the predictive assessment of groundwater level. The role of anthropogenic component of infiltration recharge due to losses from water communications, especially in local areas, is investigated, which in the future will be reflected in engineering measures justification.

Experience in Implementing the Method for Determining the Integrated Risk Assessment of Engineering and Geological Processes for the Territory of the Volyn-Podilsky Plate

“…Information on the state of natural landscapes should be the basis for assessing their importance in the system of ecological and geological conditions of territories, the formation of geochemistry of the modern landscape, definition and interpretation of migration conditions of chemical elements and their compounds. At the same time, such information should be used as a morphogenetic basis of the landscape-geochemical map [5].…”
