Settlement prediction of vertically loaded pile groups for Thermal Electric Power Station - Gdansk - Poland

摘要

This paper presents a numerical procedure to estimate the settlements of a group of vertically loaded group of piles under rigid pile caps. The load transferred by foundation elements is represented by a statically equivalent system of point loads. The settlements are calculated by numerical integration of individual forces contributions which are obtained through Mindlin's equations and Steinbrenner's procedure for layered soil. The load transfer model considers that the pile toe resistance is notdeveloped until the ultimate pile shaft and cap resistance are attained. The settlement of pile head is composed by the elastic shortening of pile shaft and by the displacement of pile toe, according to Vesic's proposition. The prediction of group behavior is made taking into account the results from one load test on a single pile.
