Russian Approaches to Permafrost EngineeringGeorgy Perlshtein Abstract The basic goals and problems that permafrost engineers and scientists
are facing presently remain almost the same as they were 20 years
ago. Nevertheless, the contemporary stage of cold regions development
has specific features. One of the most important is permafrost response
to global climate changes. In this report, some new technical solutions
are described concerning construction, mineral mining, and development
of oil and gas fields, environmental protection, surveys, and other
related activities. Among them, a foundation on sandy back-filled
ground in Yakutsk is exemplified. Most erected buildings here have
not undergone any dangerous deformations over a 20-year period of
operational experience. The methods of roadbed operation were improved
for the railroad lines Obskaya-Bovanenkovo, Chara-Cheena, and others.
Some new features of thermokarst, frost heave and other dangerous
cryogenic processes have been revealed in connection with pipeline
construction. This has induced the development of permafrost monitoring.
In any event, the main principle of Russian specialists is to apply
such scientific-technical decisions that utilize the site's natural
conditions. This helps alleviate the negative influence of permafrost
and uses favorable features of the territory |
