Road operation in areas with frozen soils requires monitoring of subgrade soils due to seasonal changes of their properties as well as development of negative cryogenic processes. Monitoring subgrade soil properties and condition is most effective using GPR. The results of theoretical and experimental studies of subgrade soils of roads in the North revealed the main wave characteristics of GPR data...
An ice road will be organized across bodies of water in winter to enable the movement of vehicles and people, thus creating the proper living and operating conditions for the local population and industry. Possible loads and measures necessary to ensure the rigidness of the ice must be considered when setting up such crossings. This article produces the results of research on the ice crossings using...
High-resolution geophysical data can aid in the study of faults by providing subsurface information about the geologic structure. The paper presents the results of a GPR investigation of fracture-dislocations and tension zones in the Russian North-East (Republic of Sakha (Yakutia), Anabar region), which contain structural traps for minerals. It is shown that under conditions of indistinct geomorphological...
Laboratory research was conducted on rock samples of varying humidity in a refrigerating chamber, with subsequent defrosting at a temperature of +22°C. The data presented was acquired with an OKO-2 GPR with a center frequency of 1200 MHz on river sand and rock sand of varying humidity (from 3 to 20 %) and with a change in temperature. The results of the research showed a significant difference between...
This article illustrates the experience of using GPR in areas of gold deposits at the Allah-Yun and Bolshoy Kuranah River (Yakutia, Russia). We considered the methodical base of dredge site GPR in the permafrost zone. The studies identified and mapped rocky outcrops and areas of boulder encrusting matter and also defined the geometry and areas of bedding rock fracturing. A method of GPR mapping of...
