TECHNICAL CONDITION OF THE ARCHITECTURE MONUMENT IN THE LANDSLIDE ZONE IN ODESSA

Abstract

The article presents the results of a survey of the monument of architecture and urban planning of local importance. The main defects and damages of the building are analyzed, its technical condition is determined. The causes of damage to structures are also was identified and recommendations for their elimination are provided.

Preservation of monuments of architecture and urban planning is the main component of the long-term comprehensive plan for the development of the Odessa region until 2025. Therefore, the study of the technical condition of historical buildings of past years of development is an urgent problem.

In September-November 2020, employees of the Research Institute of Fundamental and Applied Research of the Odessa National Maritime University examined the main building of the complex of buildings at st. Gogol, 2 in Odessa. The purpose of the survey was to determine the technical condition of the building, establish the causes of damage and develop proposals for restoring the operational suitability of the building.

The building is located within the plateau at a distance of 10 ... 15 m from the landslide slope. The building is four-storey with a basement. Structural scheme - a stone building with load-bearing longitudinal and transverse walls. The base of the building is low-strength shell limestone. The foundations are tape, made of low-strength shell limestone on a lime-sand mortar.

During the survey, it was revealed that the foundations are characterized by the presence of small cracks with an opening width of up to 2 mm, there are chips, local potholes, violations of the plaster layer of the basement. There is no waterproofing of foundations. The walls also have vertical and horizontal cracks. In the roof truss system, the places of penetration of atmospheric precipitation, traces of moisture, rotting and destruction of roof structures are marked.

The nature of cracking and deformation of the outer transverse walls of the building indicates subsidence of a part of the building, but the deformations are within acceptable limits. To restore the operational suitability of the building, it is recommended to perform the proposed set of works.
