Operation of the old buildings of the Lviv city is close to a century conditional term. The owners of these buildings, regardless of their form of ownership, should follow structural safety of buildings associated with the reliability of operation. They must have the appropriate specialists or hire them to determine the technical building condition of the old building. These buildings have long been subject to examination to continue the period of efficient service of housing.

Purpose. The aim of the research is the analysis of integrated observations of parameters of physical fields in the CSG of Transcarpathia, the establishment of the space-time dependence of observable quantities, identify their characteristics and connections of these fields with the geodynamic situation in the region to build a geomechanical model of the system of Transcarpathia, the process of accumulation and release of energy of elastic-deformation processes.  Methodology.

The main aim of this work is the study of dynamics of crustal movements in Europe for the period from 2000 to 2010. Absolute and regional annual vectors of velocity of displacement of permanent stations are estimated and schematic maps of annual rate of displacement vectors are created, conditional crustal blocks (CCB) which stable kinematics of horizontal displacements of permanent stations are selected. Average annual velocities and directions of movement of these blocks are estimated. These results will be further used to study the crustal deformation in surveying region.

GNSS has become common practice in determining movements and deformations of the earth crust in the global and regional scale. The results of observations at 147 permanent GNSS-stations located in Europe have been used to calculate the parameters of crust deformation. Using the Delaunay triangulation, our study region was divided into a network of triangles. Calculated velocity of the dilatation are belonging to the centers of the elementary triangle which was divided our study region. Schemes of the dilatations distribution in Europe from 2000 to 2010 have been created.

Purpose. The aim of the research is to estimate parameters for seismic dislocations, for example of strong earthquakes in the Turan platform and adjacent mountainous part of Western Tien-Shan, as well as identifying the relationship between the magnitudes and lengths of breaks for pleistoseist zones. Methodology.

In this article are propose presition system for the mesuring deformation.

Obtain working formula for determining trustworthiness information about vertical drift of the pipe bore-hole out of account of the own weight.

Made analytical review about basic models determination of the influence subsidence of the surface over deformation drilling column oil-gas bore-hole.

We studied the gradient dependence of the effective viscosity η for the diluted solution of the polystyrene in toluene under three concentrations ρ = 0.5∙105, 1∙105 and 2∙105 g/m3 and for four polystyrene fractions with average molar weights М = 5.2∙104, 4.4∙104, 3.3∙104 and 1.8∙104 g/mol, in the temperature range of 293–308 K. The experiments have been carried out with the use of rotary viscometer “Rheotest 2.1” at various cylinder rotation angular rate ω (r/s).
