Abstract:
The article presents the results of vertical static load tests of
diametral and deep bored piles specially conducted at the construction site
of EXPO-2017 in Astana, Kazakhstan. The methodology for determining
the bearing capacity of the pile is summarized. Bored piles with a length of
31.5 m and a diameter of 1000 mm were tested. Vertical static load tests
were conducted for the following load configurations: Bidirectional Static
Loading Test (according to ASTM D8169), Static Compression Loading
Test according to ASTM D1143-07 and Static Loading Test according to
GOST 5686-12. The method presented in the paper can serve as practical
guidelines to assess the capacities of bored piles installed in the field. This
geotechnical investigation is important for understanding the soil-structures
interaction on difficult soil ground conditions related to the construction
sites.
