ВЛИЯНИЕ ПРИРОДНЫХ УСЛОВИЙ ТЕРРИТОРИИ НА ПОДТОПЛЕНИЕ ИСКУССТВЕННЫХ ПОКРЫТИЙ АЭРОПОРТА г. ЧИТа

Abstract

he study of flooding of engineering structures as a dangerous engineering and geological process and the prevention of emergencies and environmentally adverse consequences is an important task of national economic importance. The purpose of this work was to study the natural conditions of the area of the Kadala airport in Chita to identify the main causes of flooding of the artificial runway (IVPP). The object of research was the near-surface part of the geological environment, the subject-the factors of formation of hydrogeological, engineering-geological and geocryological conditions. In the course of the research, the following tasks were solved: 1) identification of factors that affect flooding; 2) assessment and proposal of acceptable protective measures. The research methodology included: collection and analysis of materials from previous engineering and geological studies; interpretation of satellite images; field survey of the artificial runway and adjacent territory; analysis of hydrometeorological conditions. As a result of the research, the factors that lead to flooding of the south-eastern section of the airport, and in winter to the formation of ice and deformations on this section of the airport’s artificial surfaces are determined. The identified factors are divided into regional and local. The hydrogeological and engineering-geological conditions of the territory and their dynamics over time are considered. It is determined that the main factors of flooding are the creation of barrages in the path of the movement of underground water and the intensive freezing of the soil on the section of the artificial runway. Recommendations for the stabilization of the ground base on this site and measures for the engineering protection of the airport territory are given. The implementation of the recommendations will ensure the accident-free operation of the artificial runway and improve the environmental condition of the settlement adjacent to the airport from the south-east
