An Appropriate Solution of Designing and Accomplishing of a Geodetic Network for Monitoring of the Constructions

Abstract

The monitoring of the behaviour of spatial structure of a building is a systematic activity of collecting and capitalizing of information derived from observation and measurements of some phenomena and sizes that characterizes the structure in the process of interaction with the environment and technological developments. Verifications by calculating the amount stress values in the characteristic sections of the building are confronted with the results of tests on models or test sections. These are - currently - followed by observations made by means of measures installed both in the body of the building and outside it. Hypothesis verification models are supplied by statistical tests. On the measurements compensation there are formulated several hypotheses. To validate or not the results obtained after compensation is necessary to verify such assumptions. To detect possible deformations (displacements) occurring between two networks, observed at different times, the analysis should be performed only on the remaining common (identical) points in the interval T i and T i + 1 . In principle, comparing the coordinates (i.e. altitudes / heights) of the network points determined at different stages and investigate whether they form or not congruent figures. The difference between the determined parameters for network points should be within the margin. The safety margin is calculated according to the empirical standard deviation. If this does not fall within safe limits, the statistic test does not indicate anything other than that deformations have appeared in the network. Â
