EXPERIMENTAL STUDY OF BEARING AND DEFORMATION BEHAVIOR OF SQUEEZED BRANCH PILE AND ITS BEARING CAPACITY CALCULATION

Based on the results of static loading tests and measurement of axial forces, the load-transferring mechanism and deformation behavior of vertically loaded squeezed branch piles are investigated and discussed in this paper. An equation is developed to calculate the vertical bearing capacity of a single pile. The obvious time effect and end-bearing behavior of bearing disks are pointed out by means of analyses. The high bearing capacity and S-shaped Q-S curve of squeezed branch piles are highlighted.
