METHODOLOGY AND SOFTWARE GPR MONITORING OF CRYOGENIC PROCESSES IN THE SUBSURFACE SOILS
In this article, the developed complex of program and methodical providing for GPR researches in the monitoring mode is considered. The basis of the complex is original technique of monitoring of permafrost soils condition, the advantage of whose is determination the properties of the soil each point of the studied cross-section with using seasonal measurements (autumn and spring). Seasonal measurements allow to estimate most objectively a certain type of permafrost-soil cut test sites of the highway, reflecting the characteristics of the condition of the soil massif (frozen, plastic-frozen and thawed soils), heterogeneity of road base (sites suffusion processes, the presence of water-logged soils, degradation of permafrost), to determine locations of underground engineering communications. The results of testing of the complex are presented as an example GPR survey of a site on 238 km of the soil highway «Vilyuy». GPR measurements on a site of 238 km are executed in October 2015 and in March 2016 in contact with a highway surface. The result is shows the possibility of visualization of GPR data monitoring in graphs of soil humidity on a sensing profile with reference to the studied sections of the highway, and also presenting the results using geographic information system Quantum GIS overlay on OpenStreetMap.
