Abstract


The article considers the project a new railway station on problematical soils of Astana, as well as light rail LRT Project. This article includes a summary of dynamic and static tests of driven and bored piles. Also, it is given the methodology for determining the bearing capacity of piles. As an example of these methods, the results of the dynamic, static and new PDA (Pile Dynamic Analyzer) test of teamwork and piles of soil carried out on the construction site “The new railway station in Astana” and Project light railway LRT (Light Railway Transport) planned to build in time for the World Expo in Astana EXPO-2017. This paper presented a short description of changes to the concept of Kazakhstan pile foundation design and to use PDA and DLT and SLT pile load tests. By georadar survey was funded the areas which reported a hard rock at a depth of 16 meters and other soil layers.

Conclusions


Existing pile foundation standards practiced in Kazakhstan are out-of-date and are in urgent need for modernization. This paper presented short descriptions of coming changes to the concept of Kazakhstan pile foundation design. PDA and DLT are more economical issues than SLT. PDA dynamic test shown more confirm to SLT result than traditional DLT test. Four geological compartments are indicated. Within the green, grey and brown areas the absence of hard rock has been assumed and it is assumed that a layer of gravel at a depth of 12.8 meters will be thick enough to provide sufficient bearing capacity for the LRT piles. Areas shown in blue are reported to provide hard rock at a depth of 16 meters that will be sufficient to support the piles.
