Ensuring the operational suitability of buildings, railways and bridges in of the Arctic zone in conditions of global warming

Abstract

The effect of global warming, the trend of which in the western part of the Russian permafrost zone will be at least 2оС / 50 years is in the focus of the article. The main purpose of this study is to prevent the thawing of the permafrost base of buildings and structures of the transport infrastructure. It requires provision for strengthening the bases and foundations of objects erected according to principle I. The article provides an analysis of various reinforcement options. The elements of reinforcement (thermalstabilizers, injection wells) are shown to introduce significant thermal and deformation disturbances into the base, which requires a correct calculation justification of the reinforcement project.
