Study On The Construction Control And Management Of Self Anchored Suspension Bridge

Suspension bridge structure has the characteristics of good performance,large capacity,light and beautiful,strong earthquake resistance,diverse structure and good adaptability to terrain,and it is often used in many traffic obstacles such as big river,alpine canyon and bay port.But the general type of ground anchor suspension bridge,the need to build a large amount of anchor to anchor the main cable,which resulted in poor geological conditions.The basic structure of the anchor structure is very large,often become a difficult project.Suspension bridge anchor and anchor foundation occupies a considerable part of the project cost,become an important factor affecting the structural economics of the suspension bridge.In urban areas or tourist areas,the construction of bulky anchor,the environmental beauty will also have a negative impact.Therefore,in some of the span requirements are not too large,self-anchored suspension bridge program due to the novel structure,beautiful appearance become a competitive bridge program.In view of the rapid development of domestic self-anchored suspension bridge and the large number of design adopted,and the research lag,this study intends to in-depth study of several key technologies in the construction of self-anchored suspension bridge,to fill the construction of self-anchored suspension bridge Theory and method of blank,to further improve the domestic self-anchored suspension bridge design theory and construction methods.The main contents of this study include the study of nonlinear analysis theory and method of suspension bridge,the key technology research of cable stock and the key technology of boom tensioning,and put forward the optimal adjustment scheme.
