OBSERVATIONS OF DEFORMATIONS OF BUILDINGS AND STRUCTURES
Observations of deformations of buildings and structures
In the process of construction and operation of objects of increased responsibility, it becomes necessary to carry out observations of their deformations (sediments, shifts, rolls).
Geodetic observations of deformations and displacements include measurements with the help of geodetic instruments of horizontal and vertical displacements, both of buildings under construction and of structures in the zone of influence with the aim of:
Timely establishment of critical values of deformations;
Identify the causes of deformation;
Development and adoption of measures to eliminate negative processes.
Allocate observations for vertical (sediments) and horizontal (shifts, rolls) displacements.
Geodesic measurements of the sediments of the foundations of buildings and structures are performed using precision digital levels, and shifts and rolls – using high-precision robotic electronic total stations.
To obtain a complete picture of the state of the surveyed object as a whole, geodetic monitoring of the cracks in its facades is carried out simultaneously with observations of the subsidence of the base of the building.
As a result of observations of deformations of buildings and structures, a technical conclusion is drawn up on the status and forecast of the development of the identified displacements, recommendations are being developed for carrying out appropriate measures to prevent the negative consequences of critical violations.
