The analysis of the results of numerical experiments shows that the values of additional vertical displacements of the group of structures vary in the range of maximum values from 4.4 to 8.8 cm. The minimum additional displacements were received by the structures in case of thawing of the permafrost soil roof to a depth of 1 meter. Maximum additional displacements were obtained in case of thawing of permafrost roofs to a depth of up to 5 meters. As the thawing depth increases, the magnitude of additional settlement of the structure’s decays. These results are in good agreement with the data of field observations. 4. Conclusions The numerical experiments allowed us to draw a number of conclusions. The constructed finite element models and the results of numerical experiments are in good agreement with the observation data on natural objects and those given in the literature. It follows that this approach can be used to design systems for monitoring the deformed state of construction objects. Further, it can be concluded that the values of settlement of structures are within the range, which is quite easy to control by hydraulic leveling systems. This is also confirmed by the cryolithozone melting rates and the response of monitoring systems to the development of such processes. It is also important to conclude that the settlement of the structures is not uniform. This also allows us to conclude that it is legitimate to use hydraulic leveling systems to control the relative settlement of structures. Such systems allow to control the deformed state of structures online 24/7.
