Abstract

Relevance of the topic. Engineering-geological researches for the construction of any object obligatory therefore are always relevant. Formulation of the problem. The distribution, thickness and lithology of Quaternary sediments on the territory of Chernihiv often change by area in the incision (on depth), what is dangerous in the construction of various buildings or structures. To provide the fastness of constructed objects, it is necessary to study in detail the geological conditions of construction before the start of the construction. Analysis of recent researches and publications. Publications that relate to the topic of the article are missing. Emphasizing of previously unexplored parts of a common problem. A common complex problem that is not sufficiently solved for the territory of Chernihiv, Chernihiv region is the distribution, thickness and lithology of the Quaternary sediments. Statement of a task. Detailed researches of the geological structure of the site in microdistrict "Masany" in Chernihiv between the Krasnoselsky and Glebov streets (to Andrusenko Street) for the construction of multi-storey residential buildings. Statement of the main material. According to geomorphological features, the site of work is located on the Chernigov-Gorodnya moreno-zander plain. The geological incision of the site to a depth of 18 m is composed of modern man-made, upper- and mid-Quaternary, Neogene sediments. In it, according to the results of drilling, static sounding and laboratory research, 11 engineering-geological elements were identified. The area of research on the complexity of engineering and geological conditions belongs to the second category. Conclusions according to the article. According to the results of the studies performed, it has been established that the thickness of the soil (sediment) in the section and in area is not uniform. Soils IGE-3-6 subside with additional loads. Groundwater, which is located at a depth of 4.2 - 8.1 m, during intense precipitation and melting snow can rise to a depth of 1.4 m. When designing buildings and structures, there is possibility of flooding of the territory therefore, it is necessary to provide for waterproofing foundations and basements, water regulation of surface runoff, arrangement of water-carrying communications in order to prevent water losses. Water is non-aggressive to all brands of concrete and cement, reinforcement of reinforced concrete structures.
