Abstract:
The article presents the results of the dynamic (DLT), static (SLT) and a new
method of Pile Dynamic Analyze (PDA) tests of the reinforced concrete piles with rectangular
section 30 x 30 cm and length 12m driven piles for problematic soil conditions of the “New
Mosque” in Astana city. Field test are carry out in accordance with requirements GOST 5686,
for definitions of bearing capacity of the piles in accordance with requirements SP RK 5.01-
03-2013 and ASTM D4945. The test method is similar to that used on driven piles with the
monitoring of hammer blows and subsequently analyzing the pile response to the stress wave
propagation. A separate hammer or drop weight is usually brought to site to allow the
dynamic load to be applied to driven pile. According to the results of tests were determined
the possible depth of penetration and bearing capacity of driven piles. This geotechnical investigation is important for understanding the soil-pile interaction on difficult and problematical
soil ground conditions related to the construction site.
