Computing the value of uneven raising of building consisting of nine segments deflected from vertical due to mining exploitation

Abstract Deflection of buildings from vertical is a common damage caused by underground mining. Its removal consists in tearing the building apart at level one storeys, most often basement, and then unevenly lifting part above plane with use piston hydraulic jacks. One conditions for properly carried out rectification correct computing height individual corners building. The subject article deflected large projection (64.0 m × 41.9 m). nine dilated segments, which are functionally related. width expansion joints between segments about 10 cm. deflection occurred as result deformation mining area. Due to significant building, each segment not same. It was decided that would be removed uneven raising structure jacks mounted walls. method value presented. In first step identified. Than were divided into groups, due their functional solutions. Then, group, average determined. On basis this deflection, values Described procedure made it possible minimize number steps will appear segments. Thanks this, regain functionality after carrying planned renovation.
