The study outlines the technology for increasing bearing capacity of subgrade foundation on high-temperature permafrost soils in Arctic zone with objective to develop technological regimes strengthening weak embankments, allowing regulation loads during construction facilities soils. research methods included system analysis and specific organising zone. described methodology consists step-by-step modelling calculation parameters geotechnical monitoring condition determine maximum...

We suggested earlier a new sustainable method for permafrost thermal stabilization that combines passive screening of solar radiation and precipitation with active solar-powered cooling the near-surface soil layer thus preventing heat penetration in depth. Feasibility this has been shown by calculations, but needed experimental proof. In article, we are presenting results temperature measurements obtained at implementation outside area which actually meant higher loads than area. have is...

Stabilization of permafrost soils the roadbed base, constructed with assumption thawing, thanks to improvement their strength characteristics, requires development and selection rational structural technological solutions. The objective study was analyze effectiveness use vertical columns crushed stone in zone influence on characteristics soil base. has used general scientific methods, modeling, simulation comparative analysis. This article proposes a method for improving properties base...

The reasonability of technological control for geotechnical structures foundation strength targeted development during the construction is shown. procedure weak soils stabilization and real time monitoring processes management proposed using example Northern Latitudinal Path.

[For the English abstract and full text of article please see attached PDF-File (English version follows Russian version)].ABSTRACT An intensive technological regime for increasing stability weak soils is proposed to ensure safety roadbed on site with eternally frozen base Northern latitudinal railway Salekhard-Nadym. It shown that it necessary take into account talik zones at design stage, which can cause various deformations. On basis fundamental principles mechanics soils, regularities...

The transport facilities construction in the Arctic zone regions of Russian Federation is a complex engineering task. This complexity caused not only by competent choice structural and technological solutions for improving foundation soils but also rational organizational solutions, which turn affect timing facility construction, its cost, efficiency Far North Federation. During permafrost zone, building materials often require delivery to site using rail, road, water transport. Construction...

Construction in the regions of Far North is characterised by numerous natural barriers, presence permafrost soils foundations structures, lack infrastructure and extreme climatic conditions. Thus, most urgent task both design construction, further operation transport Arctic to ensure reliability foundation structure. To structures designed on soils, it necessary carry out thermophysical calculations make forecasts influence temperature processes soils. The territory (PFS) occupies a large...

In the current system of road construction, actual task is to choose model construction company correctly, as well establish methodology for processing results modeling identify its (company) production structures. The Pareto optimality principle be considered.

Intense construction technology was developed in IPSS MIIT for weak foundations of geotechnical structures strengthening and consolidation speeding up during the period. The experience intense regimes application PVT Transstroymechanizatsia has shown draught acceleration shortening subgrade construction. Let us show that theseadvantages allow gaining technological economic positive effect.
