Experimental study on bearing behavior of long rock socked pile with O-cell test method

摘要

The O-cell method which was applied on the pile testing was introduced, including the basic principle, test device and test technique. The advantages of O-cell method compared to traditional pile testing method were also illustrated. Based on the project of offshore structure in Mozambique, the O-cell test was performed on the long drilled rock socked pile. The results were converted to the traditional load-settlement curve to analyze the bearing behavior and load transfer characteristics. The regularity of axial force and shaft friction of rock socked pile were also revealed.
