The study of the soil of the base of the Krasnoyarsk territory and the method of strengthening

Abstract

Railways in Russia rightfully occupy one of the key places in the national economy in connection with the geographical conditions, technological features of the economy and the possibility of maximizing the use of the country's transit potential. The problem of modernizing the transport system of Russia, its adaptation to the requirements of the functioning of the national economy and foreign economic relations is becoming increasingly relevant for the regions of the North. As part of the main stage of the expedition “Transpolar Highway”, conducted by the Russian Geographical Society (RGS) together with the Russian University of Transport (RUT) from September 19 2019 to October 15 2019, specialists from the Russian University of Transport examined the territory of the Krasnoyarsk Territory to assess the possibility of designing and building tracks messages in these regions. The lack of transport infrastructure, the unpredictability of the behavior of frozen soils during freezing-thawing, the presence of weak soils in the foundations of structures, difficult climatic conditions, all these factors determine the complexity of construction in these regions. This article describes the determination of the strength characteristics of soils using a dynamic Panda penetrometer-density meter in the field. Conclusions are made about the appropriateness of using these soils in the foundations of structures. Due to the lack of quarries for the production of crushed granite in the Norilsk region and the difficulty of transporting this material, the use of Norilsk metallurgy waste as a replacement for crushed stone was analyzed. The results presented in the article are part of the dissertation research I. Artyushenko "Reinforcement of the subgrade base with vertical columns of crushed stone in areas with permafrost soils"
