Analysis of the Results of Geotechnical Monitoring of "Lakhta Center" Tower

Abstract

The paper contains the results of long-term monitoring during construction of the "Lakhta Center" tower in St. Petersburg. A brief description of the geotechnical monitoring system is provided, including types, quantity and location of the measurement equipment, methods of placement within structural components, and reading techniques. The comparison between the monitoring data and calculation results obtained by various methods demonstrated their qualitative and quantitative differences. A hypothesis regarding the effect of a number of factors on pile performance within the pile field is proposed. The recommendations on performing geotechnical calculations when constructing high-rise buildings are provided.
