Application Of Pressure Decentralized Anti-floating Anchor In Engineering

In today's civil engineering construction, ground anchor has been growing a wide range of applications. A long period of time, tension-type bolt has been widely used by domestic, analysis of relevant research has been more mature and fully. However, as our country's water conservancy, transportation, communication and other infrastructure to increase the strength, slope, dam, bridge, tunnel, deep foundation and construction of the structure of anti-dumping, anti-buoyancy, anti-slip and other construction projects will make higher demands to geotechnical anchor, which are the traditional type of bolt tension difficult to solve their own problems. Therefore, the development and research of the mechanism of the force with better performance and a new type of bolt has become important from.Distributed pressure bolt is a new type of anchoring system is a single composite anchor, and general tension-type, anti-floating bolt pressure than the pressure of anti-floating bolt dispersed by force and transmission mechanism more reasonable, more uniform distribution of bond stress, anti-corrosion performance and durability can be enhanced.This paper reviews the pressure bolt decentralized structure in China against the floating of the practical application of engineering and research on distributed pressure bolt stress distribution and the analysis of bearing capacity. In this paper, the Beijing Poly building the basis of the new anti-floating projects, from the structure, mechanism, design computing, engineering materials, construction techniques, on-site tests and anti-corrosion protection of the pressure bolt decentralized system had an in-depth research and discussion and analysis of the pressure bolt decentralized applications in engineering features and advantages.Dispersed by the pressure of anti-floating anchor design and analysis of the Project to verify the pressure distributed application of anti-floating anchor the advantages of the project. At the same time, dispersive pressure as well as anti-floating anchor to provide a study of ideas, and to spread the pressure of anti-floating anchor further application in the works to provide some useful suggestions and references.
