Field Experiment Study on the Bearing Characteristics of Squeezed Branch Pile in Loess Area

Abstract

The load-transferring mechanism under the action of vertical load and the role of bearing load by bearing disks in loess area were analyzed based on results of field static loading test of the squeezed branch piles. The results indicate that load transfer law of squeezed branch pile is transferred from top to bottom, and load of bearing disks is about 60 percent of the top load of the pile, stress superposition efficiency existed between bearing disks, and the minimum critical spacing of disks is 2D (D is the diameter of the bearing disk), the estimated bearing capacity of the squeezed branch pile is higher than the measured value.
