This paper presents the complex analysis of diverse field loading tests of
four with diameter 600 mm CFA bored piles. Four static compression pile (by ASTM
D1143) loading tests were carried out on the construction site. Static loading tests applied
load to a deep-foundation element gradually for measuring foundation settlement. This test
is used to measure the axial deflection of a vertical deep foundation when loaded in static
axial compression. This vertical compression pile maintained load test is usually carried out
to ensure the structural and geotechnical soundness of the pile and also to predict settlement
of other piles. Applied load and head movement are measured for static axial compression
load tests. The load-settlement and the load-displacement curves were obtained from field
tests. Comparison of bearing capacity of bored piles with different length in problematic soil
conditions of West Kazakhstan were discussed in this paper. The analysis showed that the
bearing capacity of bored piles with different lengths corresponds to the design requirements. These investigations are important for understanding of soil-pile interaction on problematical soft soils ground of Aksai, Kazakhstan.
