APPLICATIONS OF PILE DYNAMIC AND STATIC TESTS IN ASTANA, KAZAKHSTAN

Abstract

This paper includes the short summary about dynamic and static soil tests by driven piles with square cross-section (30×30 cm and length of 12 m) commonly used for the problematic soil conditions of Astana. The definitions and determination methodologies of the pile bearing capacity by aforementioned methods were also given. As an example for those methods, paper describes the results of the dynamic, static and the new in Astana PDA (Pile Dynamic Analyzer) tests of soils by piles performed in the construction site of the “New Railway Station”. The possible depth of piling and piles bearing capacity were determined according to the results of tests. As well as the recommendations for the device of working piles of construction project were issued.
