This paper presents the complex analysis of diverse field loading tests of ten large diameter
deep bored piles on CFA technology at the Karachaganak Processing Complex (KPC), Aksay, Kazakhstan.
On the basis of core sample analysis and seismic studies, the geological conditions of this field are varied and
complicated. According to the project design, the field tests of CFA bored piles with diameter 600 mm,
length from 15.51 m to 21.85 m were performed by two static laterals, four static tensile and four static
compression pile loading tests. Static loading tests applied a load to a deep-foundation element gradually for
measuring foundation settlement. The static loading tests were performed by ASTM D1143, ASTM D3689,
and ASTM D3966. In this paper are shown the load-settlement and the load-displacement diagrams from
those field tests which give the possibility to identify the bearing capacity of piles at this ground. The
analysis showed that the bearing capacity of bored piles with different lengths corresponds to the
design requirements.
