EXPERIENCE IN DESIGN OF A HIGH-RISE BUILDING WITH A PILE FOUNDATION CONSISTING OF PILES OF DIFFERENT LENGTHS

The article presents the experience of the foundation designing for a high-rise building. After the construction of the underground part of the building, the project was halted for several years. When construction resumed, the height was increased, and it was decided to utilize the existing 28.5-meter-long piles by supplementing the pile field with longer ones. The article highlights the key aspects of the entire foundation design and calculation process, during which several foundation options have been reviewed. Also, the article presents the results of pile testing, including their modeling and validating this model. Based on it, the model of single pile has been validated and the equivalent pile model has been verified. After this, prediction of settlements has been given.
