Identification Of The Reference Base For Horizontal Displacements By “All-Pairs Method”

In studies of movement essential element of the correctness of the obtained results is correct identification of the reference base. One method for such identification, referred to as “all-pairs method”, is to examine the insignificance of the mutual displacement of potential reference points in all combinations of pairs. It is a well known exact method of identification, but its use in practice is limited to the study of vertical displacements. In this work we present the possibility of application of this method in the study of horizontal displacements. Numerical example illustrates the calculation procedure of the proposed method.
