Application of Static Compression Load Test of Joint Piles in Seaport “Prorva” in the Caspian Sea Coastal Area (Western Kazakhstan)

抄録

2 segments precast concrete piles consist have been applied as foundations for “Cargo Transportation Route for of the north-eastern part of the Caspian Sea North Caspian Marine channel with berthing facilities Cargo Offloading Facility” (CaTRO, COF) the “Prorva” oilfield, Atyrau region in the Caspian Sea Coastal Area, Western Kazakhstan during November 2016 to July of 2017. This paper presents that seven characteristics engineering-geological elements (units) are identified based on the geological setting and the borehole logs. Testing of soils by piles was submitted by engineers of the LLP “KGS-Astana”. The main purpose of this paper is to present many aspects of foundation construction in low temperature condition and freezing soil in winter season, to analyze the bearing capacity and a settlement of low temperature -5℃, -10℃. Pile testing was carried out in winter, when local climate and soil condition make is a 1 m. depth frozen soil make impact to the changing a ratio of ultimate bearing capacity and settlement. At the construction site of Seaport ''Prorva" the static compression load test method was applied. In practice, SCLT is one of the widely used methods for analyzing of pile bearing capacity. This paper presents the result of the analysis of 2 joint concrete piles of number (d/36), (k/3). SCLT testing was holding on 2 cycles.
