ABSTRACT
Mathematical statistics is now a standard tool without which modern science, technology and economics cannot do. Article serves to become familiar with the theoretical foundation deformation investigation, theory of errors and smoothing. Levelling network can be processed by the method of least squares (LSM) based on regular Gauss - Mark Models. The process consists of geodetic networks processing the measured values in general construction of a theoretical model of deterministic and stochastic, and then a statistical model. The only way to get information about the concept is a direct measurement using an implementation of the vector. The processing of measured elevations in the network was based on the general relationship that are a function of elevation offset the high points and measurements are burdened with actual errors ε . However, in terms of an effective approach in defining the date geodetic network is preferable to use model settlement intermediary measurements with the conditions, which allows a more flexible approach in defining the date geodetic network and also allows examining the stability of reference points within a single process. Date elevation is assigned based on the network purposefully elected, each independent of conditional equations lying T G on the estimated parameters. Track extremely slow forms, eg. Lateral movement (mm/year) or tectonic movements of the fault structure was replicated monitoring optical-mechanical device dilatometer TM-71, which is capable of detecting motion and micro-displacement in three directions and also is able to record in the two rotation axes. Facilities should be complete information on the movement of cracks using Moire, which were successfully implemented precisely measuring instruments for cracks. Moiré effect is mechanical interference that appears in the form of black and white stripes, light induced the upstream grid. Moire density increases with the density of the grid and grid movements evoke movement strips.
