Abstract

The hydrostatic leveling method as part of deformation monitoring systems is an accurate tool for measuring vertical displacements. However, the operating conditions of the monitoring systems impose restrictions on the use of the method and reliability of its results. The article deals with the cases of practice in which there are errors in liquid level under the influence of the environment. The fundamental engineering problem of this study is the adaptation of the hydrostatic leveling method to the systems for deformation monitoring of real buildings and structures. To solve this problem, a number of models have been developed to describe the movement of liquid at hydrostatic levels, and their experimental verification has been performed. The simulation allowed to evaluate changes in the readings of the hydrostatic level depending on the external action (changes in air pressure, vibration, temperature). The results of the numerical solution to the problem of heat and mass transfer in the «hose-mixer» system have been used to estimate the possibility of equalizing the temperature of the liquid at a hydrostatic level by its stirring. Field experiments were conducted to study the forced liquid stirring in a hydrostatic leveling system, which allow marked reduction of the temperature error. Based on the results of experimental studies, the selection of liquids for hydro-leveling systems operating in the negative temperature range has been carried out. The knowledge obtained from the conducted studies can make up framework for designing hydrostatic leveling systems adapted for the deformation monitoring of complex structures.
