“…Целью улучшения свойств лёссовых грунтов является борьба с их просадочностью. Преодолеть просадочность лёссовых грунтов можно только прорезкой всей просадочной толщи сваями фундаментов [1,2]. Сооружение фундаментов на цементогрунтовых сваях по сравнению с ленточными обеспечивает существенную экономию цемента, снижение объема земляных работ, исключает необходимость изготовления опалубки и, как следствие, ускоряет выполнение нулевого цикла в 1,5-2 раза [3][4][5][6][7].…”

“…Одним из важных достоинств буросмесительного способа изготовления цементогрунтовых свай фундаментов зданий и сооружений является способность закреплять все виды слабых и структурно-неустойчивых грунтов. Буросмесительный способ наиболее перспективен при укреплении лёссовых просадочных грунтов [1,2]. Он может применяться как для сооружения новых свайных фундаментов, так и для реконструкции существующих.…”

The review of soil types prevailing in Western Siberia of the Russian Federation is presented. The compositions and physical and mechanical properties of soils are analyzed. Special attention is paid to loess subsidence soils. The problem of obtaining a homogeneous cement-ground mixture is formulated and set. The technological scheme of production of cement-ground piles of foundations of buildings and structures by drilling-mixing method with mechanical activation is considered. Considers methods of strengthening the loess subsidence of soils. Methods for studying the properties of cement-based piles of foundations of buildings and structures are formulated. A multi-factor experiment was conducted to evaluate the parameters that affect the properties of cement-based piles. Based on the research results, conclusions and recommendations are formulated.

The scientific article presents the results of the development of a method for improving the properties of soil-cement pile foundations by the drilling-mixing method using mechanical activation of soil-cement mixture in filler soils. Two methods for improving filler soils are considered. The choice of the mathematical methods for the research is justified. The feasibility of a complex combination of mathematical modeling methods and experimental design to achieve the goal set in this scientific article is substantiated. The physicomechanical characteristics of soil-cement are considered: a measure of brittleness, brittleness coefficient, compressive strength, splitting strength, strength variation coefficient. Based on the research, practical recommendations are given for improving soil-cement pile foundations.

“…Stabilisation / stiffening is a mechanism leading to reduction of particle movement achieved through confinement. It is very important in geotechnical engineering as tool to improve compaction (Kumor and Kumor, 2016; Zabielska-Adamska and Sulewska, 2013) or reduce vibrations (Rybak and Pieczynska-Kozlowska, 2014). This function of geosynthetic is commonly used in road and railway engineering (Cook et al, 2016;Grygierek and Kawalec, 2017;Zornberg, 2017).…”

Stabilisation is defined as improvement of the mechanical properties of an unbound granular material by including one or more geosynthetic layers such that the deformation under applied loads is reduced by minimizing soil particle movement. Paper discuss geogrids as type of geosynthetics which when used in stabilisation function for transport applications could provide real improvement in performance of aggregate layer. Such function has been called for a quite long time as the reinforcement of subbase, base or ballast, depending on the application
