Odessa National Academic Theatre of Opera and Ballet
The unique construction of the Odessa National Academic Theatre of Opera and Ballet was built in the period from 1884 to 1887. Deformation of the building in terms of dimensions 78 x 64 m, a height of 45 meters, a volume of about 100 thousand м3 and weighing nearly 60 thousand tons started before completion of the building.
Reconstruction and repair 1900, 1956 and 60s did not stop the destruction of the building. In the walls and foundations it was formed more than 1,500 cracks total length of 3.2 km and a width of opening from 1 to 10 mm.
In 1996 – 97 years maximum drawdown of the most deformed by years of exploitation of building parts was to about 30 cm.
Analysis from the perspective of current regulations and constructive solutions to the foundation of the building showed that they did not take into account sagging properties foundations and other factors.
Institute solved a number of scientific and technical tasks of strengthening the foundations of the building without stopping work of Theater, it was developed a set of working documents, the number of which was 234 working drawings.
In the draft in a way to strengthen the foundations via piles Institute was given patent of Ukraine number 39762A.
Due to the large volume of work of strengthening the foundations, their performance attracted six executors. None of them had enough experience. Therefore, RIBP team was constantly working at the construction site. Their main task was to control that work was quality.
Works to strengthen the foundations of the theater began in August 1998 and completed in October 2001
The total volume of construction work is characterized by the following data:
- 1837 piles with total length of 26,269 meters;
- 2430 cross beams with total length of 5086 m;
- 1823 m3 of concrete structures, metal grills, joints stiffness walls.
Measurement via the most modern methods of deformation of the theater after strengthening its foundations confirmed the high efficiency of the whole complex of scientific, research, design and construction works.
