Comparison and analysis on self-balanced method and anchored pile method in Qingdao Gulf Bridge

摘要

Based on the situ results of Self-balanced Method and Anchored Pile Method on the piles of Qingdao Gulf Bridge, the test method of them have been contrasted in same cite. Compared with anchor piles method the self-balancing test is simple way which saves money and time. And the load-displacement curve obtained from the self-balanced test is closed to anchored pile test;;from the view of the sides shear resistance, the side resistance below the load cell in Self-balanced Method is less than the value in Anchored Pile Method while the value under the load cell is more than it. The proportion which tip resistance occupied in self-balancing test is more than the traditional anchor piles method, it should be considered in pile design.
