Tóm tắt
When designing and further operating communication routes and other various structures on permafrost soils, the most urgent problem is to ensure the reliability of the roadbed. The complexity of construction in the Northern regions is due to the presence of permafrost soils in the foundations of structures and a large number of natural barriers, extreme climatic conditions and lack of infrastructure. The territory of permafrost distribution occupies a large part of the territory of Russia, therefore, the development of new areas and the expansion of the network of communication routes is an important strategic task for the state. Today, the priority region in terms of economy and strategic influence is the Arctic territory of the Russian Federation. Due to the numerous oil, gas, and ore reserves, the Russian Arctic can be called the economic center of the Russian Federation. The choice of design principles, structural, technological and organizational solutions, including the prediction of deformability, ensuring the stability of the roadbed and the creation of competent organizational schemes, should be economically feasible and the most optimal for a particular object and the region of its location. The article discusses the principles of design on permafrost soils. The analysis of technologies using different design principles is carried out. The influence of these technologies on the soils of the foundation of the roadbed is modeled and the effectiveness of the technologies under consideration is shown.
