| Abstract: | Based on the cumulative evidence of O-cell load test for rock-socket bored piles with large diameter and extra length for a bridge project, this paper introduces the theory of O-cell load test and the method of confirming the load. The po- sitioning of loading equipment and the technology of boring and casting of long length rock-socket bored pile are also dis- cussed and some views of the author are proposed to provide reference for similar projects. |
