ABSTRACT

The subjects of deformation monitoring are either natural objects such as ground
deformation due to mining exploitation, withdrawal of oil or underground water, active
tectonic plate boundaries, glacier movements etc., or the man-made objects such as dams,
bridges, tunnels and other complex engineering structures. The results of deformation
monitoring are directly relevant to the safety of human life and environment protection.
The bridges are very important subjects in the field of infrastructure management. Stability
and reliability of a bridge is an imperative so that regular inspection and monitoring of the
structure are needed. Determination of bridge deformations employs different geodetic and
non-geodetic methods and instrumentation, according to requested deformation
parameters and precision of results. There are various theoretical hypotheses on the
behaviour of the structure and therefore different tests have to be done. In this paper a
static load test of three bridges in Croatia is presented. The purpose of this test is to
empirically quantify the load capacity of the structure, i.e., to verify the predicted load deformation response of a bridge. The results of load testing were obtained by
conventional (terrestrial) and satellite (GPS) deformation survey methods.
