Geotechnical Piling Construction and Testing on Problematical Soil Ground of Kazakhstan and Russia
The paper presents the results of the monitoring of construction for the unique residential building of 310 m high with 4-storey underground parking. One of the unique projects is the housing estate called “Abu-Dhabi Plaza” which started in 2011 in Nur-Sultan city. High-rise buildings pose new challenges for engineers, especially in the design of above-ground structures, bases, and foundations. The basement walls are formed with reinforced concrete diaphragm wall panels, which were supported with ground anchors. The shoring system analyses had been designed using PLAXIS 2D, which can assess in detail of the deformations that occur in soil. In the course of excavating a thick layer of soft, weak soil in St. Petersburg, Russia, instabilities were encountered in a 21 m long sheet pile excavation fence made of AU Arcelor 18. In light of the rather large depth (12 m) and areal extent (150 m by 80 m) of the excavation, such instabilities presented a significant challenge for the geotechnical engineers. This paper reviews the results of soil property tests performed in conjunction with the construction of the aforementioned large excavation, as well as the neighboring buildings. The need for continuous monitoring of geotechnical conditions using the methods of static sounding, to assess the zone of construction influence and to forecast the mutual influence of the structure being constructed on the surrounding buildings, is discussed. Finally, the raft foundation has recommended for future high-rise buildings to be constructed on competent residual soils.
