GEODESIC MONITORING DURING TEMPLE RESTORATION

Abstract

During the construction and reconstruction of real estate and especially monuments of architecture, it is necessary to conduct geodetic monitoring. These are observations of the deformations of buildings during the construction process. Such monitoring allows you to determine the causes of deviations from the design and look ahead predicting their development, as well as provide recommendations and appropriate measures to prevent critical situations that can lead to irreparable consequences. It is no secret that a new building after the completion of construction gives a draft for a certain time. This phenomenon is because the soil is compacted under the weight of a built house, so the draft of the property is considered to be completely a normal process. Geodetic monitoring of the bell tower basement foundations of the Odessa saviour's Transfiguration Cathedral begins with a geometric leveling of the appropriate accuracy class using the level H3 and checkers slats. Before performing geodetic works, the level and checkers were tested to establish their suitability for this type of work. Geometric leveling was performed in the forward and reverse directions with the obligatory control of observations at each station. Three ground rappers are attached to the territory with a reference to the initial riper a known mark of the city network. Measurements were taken not earlier than 10 days after the laying of signs. Along the perimeter of the bell tower base fixed eight deformation were marked. The leveling of these marks was carried out from four stations, also tied to pre-fixed rappers. The results of the observations were recorded in accordance with fourteen cycles. The interval between the cycles of observations corresponds to a month. The main work was aimed at studying the prediction of precipitation of deformation marks using statistical regularities with scheduling experimental and functional dependencies corresponding to the quadratic dependence of the form Н = at2 + bt + c.
