Abstract：Pile foundation is one of the most popular measures used to resist the lift load in civil defense engineering.The squeezed branch and plate pile has very excellent properties in anti-pulling, and is widely used in undergroung engineering in recent years.The static load anti-pulling tests of squeezed branch and plate pile and straight pile are studied in this paper.Based on the test results of Q-s curves and Q-Δs curves, the application limitation of the rotated plate pile in specific soil is studied.According to the calculated results and test results of the anti-pulling bearing capatity, some suggestions are proposed.
