Abstract

Summary

The intensification of natural resources exploitation entailed highways construction necessity. In areas of perennially frozen rocks development exogenetic geological processes influence over the highways operability and can lead to accidental events. Therefore it is necessary to provide projection, construction and operation of roads with correct engineering-geological data. For these purposes the operational analysis methods(decryption of satellite images), geophysical methods (electroinvestigation) and engineering-geological methods are used. Satellite images decryption allowed to receive information on geocryologic processes distribution. At the same time development problems of a detection technique of the geocryologic phenomena, definitions of characteristics of their activity and borders of distribution were being solved.

Further geophysical and engineering-geological methods are connected. As the main geophysical method the electroprospecting method of electric intubation was chosen. In a related move tngineering-geological shooting is i carried out. On development sites of rmassive wedge ice the well-drilling and thermometric researches are planned.

Satellite images decryption allowed to allocate sites of processes development , their sizes, danger of occurrence and to designate the sites of continued more precise research methods.

Geophysical surveys were concentrated on development sections of subsurface ice. At a qualitative interpretation stage the issues of space variation nature of electric properties of the environment were resolved, the cuts of apparent resistance characterizing the electric properties change of rocks on depth were received. As a result of an methods’ integration the engineering-geological conditions of the highway were studied, the range of engineering-geological and geocryologic processes development is defined, their development scales are established and an influence assessment of a highway external environment is given.
