摘要

The squeezed branch pile used in hundreds of high-rise buildings is a new type of pile with high bearing capacity and low settlement. The mechanism of bearing, compaction efficiency and loading transfer behavior of the squeezed branch pile are analyzed systematically based on the results of static loading test for exploring the connotations of the high bearing capacity and low settlement of the squeezed branch pile. It is shown by test results that behavior of bearing disks has obvious time effect and is different from other types of piles by means of calculation. Squeezed branch pile with specific property of frictional end-bearing pile bears load mainly by bearing disks, and the ultimate load of the pile is 150 ~ 200 percent of straight pile. The load shared by disks is about 60~70 percent of the ultimate load.
