Experimental Analysis Of Pile Deformation Of Pile-Anchor Bracing Structure

Reinforced concrete pile and prestressed anchor bolt supporting structure are more and more used, because it can control the deformation of pit slope Effectively, besides, it has good economic effect and wide appropriate prospect. But the theory about the mechanism of the composite supporting system can not meet the requirements of practice now. Researchers have not got an common conclusion between the design results and the results of practice.This paper introduced Failure modes of reinforced concrete pile and prestressed anchor bolt supporting structure, calculation methods and Design methods based on existing research results.The following is about the experiment. Author carried on an experiment with deformation of supporting pile In the actual supporting project, and introduced us about the overview of the project and the Site, the theoretical guidance of the experiment, experimental preparation, experiment and data processing methods and so on. The paper dealed with datas with listing of law, mapping and with the help of the analysis software come from inclinometer, and then, author mapped out the deformation curves of reinforced concrete pile in every working conditions and curves of variation of pile-deformation-maximum changing as working conditions as carrying on.At the last, Author get the design results by LiZheng software, and then, comparing with the experimental results. In the way, author get the most important conclusion which is LiZheng software s design to Pile-Anchor bracing structure is conservative, and its allowing deformation is seven to twelve times as experiments.
