Search for the Optimal Way of Mathematical Compensation the Results of Re-Leveling Performed on Geodynamic Polygons

Abstract: В рамках научной статьи представлена реализация способа уравнивания результатов повторного высокоточного нивелирования, отличная от традиционных подходов, применяемых в геодезии. Описанный в статье метод основан на использовании, в дополнение к классическим методам математической обработки геодезических измерений, метода наименьших модулей. Выбор метода наименьших модулей в качестве инструмента для уравнивания результатов геодезических измерений обусловлен исключением влияния грубых ошибок на интерпретацию рез… Show more

“…The dynamics of natural exogenous geomechanical processes and the displacements of leveling points and the physical surface generated by them is complicated by the diversity and variability in space and time of moisture and temperature fields in the near-surface layers of the Earth's crust, which are heterogeneous in composition and depositional conditions. Natural exogenous deformations are superimposed on the studied technogenic deformations of reservoirs and rock massifs and manifest themselves in complexly differentiated displacements of leveling points and the physical earth's surface, which are mistakenly attributed to the parameters of the studied deformation processes, namely: -Seasonal thawing and freezing of dispersed soils in the conditions of the Russian Arctic is accompanied by their frost heave, generating vertical irreversible displacements of standard leveling points at a rate of up to 250 mm/year and fluctuations of the Earth's surface ± (4÷300 mm/year) [2,7,8].…”

“…-Thermal and moisture exchange in the near-surface layers of the earth's crust, composed of dispersed rocks, generates in them volume deformations (swelling and shrinkage), jointly manifested in poorly studied oscillatory and short-period vertical displacements of leveling points and heterogeneous in space and time hydrothermal movements of the physical earth's surface with an amplitude of several millimeters to meters [1,2,4].…”
