Geotechnical construction and testing of piles of megastructures on problematical soil ground of Kazakhstan

This paper describes the general aspects of the pile foundation concept, technologies as CFA and DDS used in Mega-projects of Kazakhstan. Just as every civilization in the history is originated from the riverside, so the city of Nur-Sultan - Capital of Kazakhstan has been developed around the Ishim River. Also the paper illustrates comparisons between the existing field pile test results with the results of PDA and SLT by GOST. Such advanced technologies as PIT and geo-monitoring are also mentioned. As its result,. there are many bridges across the river. Also high rise building such Palace of Peace, Abu -Dhabi Plaza, Expo2017, Ministry of Transporation Buildings constructions site and other many structures founded in problematical soil ground of Nur-Sultan city. These unigue buildings need performing of deep driving and boring piling foundations. For designing of piling foundations on difficult soils are important investigations of behavior of piles by using of dynamic, static, O-cell, integrity piling tests. These investigations of interaction of piles with soil ground of new capital are important for understanding of mechanism of working of different piles on soft and hard soils of Nur-Sultan.
