GEODETIC MONITORING OF STABILITY OF THE CONSTRUCTION PIT DIAPHRAGM OF THE OBJECT

Abstract

High-rise building, today, is characterized by the construction of facilities that are higher and more complex in their geometry, and are often located in the narrow city core where numerous facilities have been built in a small area that additionally complicate the execution of construction and geodetic works. In order to obtain information on the stability of the soil and to ensure the safe construction of underground floors, it is necessary to survey the protective structure of the foundation pit. This paper describes the method of geodetic tracking in the horizontal plane, with the possibility of detecting displacements larger then 5 mm.
