Paper Title:
Experimental Study on Bearing Behavior of Large-Diameter Overlength Squeezed Branch Pile
  Abstract

Squeezed branch pile is based on the traditional uniform pile in development of a new type of pile, with a high bearing capacity, settlement of small features widely used in the engineering. Based on the actual project site static test, analyzed the vertical bearing capacity characteristics of two adjacent squeezed branch piles; By means of testing of the pile stress gauge steel embedded in different parts of piles, the axial force transfer characteristics of the body, support plate side resistance drag and play characteristics of the squeezed branch pile were analyzed. The results showed that: the branch pile Q-S curve is slowly varying type, the three branch share of the load ratio increases with the pile top load increases and then decreases, load sharing ratio of 12% or so. The side resistance increased with the pile top displacement, the curve showed significant enhancement traits. Measured friction value of two test piles is too conservative under the existing norms, the actual measured value of 1.2~1.6 times of the standardized value.
