Geotechnical surveys of the hill of St.Andrew's Church after repair and restora-tion works
Main Article Content
Abstract
St. Andrew's Church is located in the historical center of Kyiv, on the hill of the high Starokievska Mountain above the Dnieper. The location is very good from an urban planning point of view, but quite difficult in terms of engineering and geological conditions. This has caused unabated deformation processes in the structures of the monument and, as a result, numerous repairs.
In 2008-2020, a large-scale project "Emergency and repair and restoration work on St. Andrew's Church" was carried out. The goal of this project is to minimize the negative impact of natural and man-made factors on the physical preservation of the monument and its historical environment and to carry out comprehensive repair and restoration work on it, based on modern scientific and technical achievements. The following were performed within the framework of the project: unique emergency emergency works to strengthen the soil base of St. Andrew's Hill and the foundations of St. Andrew's Church, restoration of the porch, stylobate, stairs, facades, interiors and monumental painting of the church, as well as repair of utility networks and landscaping of the territory.
The article presents geotechnical studies of St. Andrew's Church after the first stage (2008-2011) of emergency repair and restoration works on the hill, which significantly changed the hydrogeological conditions at the site. Geotechnical studies have been carried out at St. Andrew's Church since the end of the 20th century. The main goal of such studies is to eliminate the influence of negative natural and man-made factors on the monument, preserve the monument and develop measures for its protection. The current method of preserving monuments is constant geotechnical monitoring. The main results of geotechnical monitoring, the reasons for the change in hydrogeological conditions on the hill are considered, recommendations for safe operation and further research at the site are given.
