Research On The Linear Control Of Construction Monitoring & Spatial Simulation Analysis

With the great development of mountain expressway and elevated road , the curved continuous rigid frame bridge has been growing up rapidly in recent years with its unique predominance of compatibility and comfortable . But it is lack of study on space mechanistic performance , because of its relatively late appearance , and the kind of bridge using cantilever casting construct is not rape even now in china .Based on Yin shuigou Bridge,by using zhe great spatial analysis software,Midas /civil 6.71, research simulation of long span and high pier prestressed concrete curve rigid frame bridge of construction stage ;With the comparative analysith between the model and the pratical engineering ,and calculation analyse the parameters, uncontrol ,influence the curved rigid frame bridge construction control accuracy . According to different parameters's infection on the geometry control and stress control for engeerining has been comparatinve analysed , and proposed suggestiongs on modifying parameters durning the construction monitoring .In the part of construction monitoring, it's been summarized in detail that successful deflectiong control and stress control on Yin shuigou Bridge. As to the curved rigid frame bridge linear control ( twisting control , bridge pier vertical control ,axis alignment control ,altitude control ) ,it's been summarized .The whole processing of the core content about the curved rigid frame bridge linear control , radle construction, contains : cradle designing thoughts , cradle assembling , cradle preloading , cradle fore shift ., the good or bad on the different style of cradle for the curved rigid frame bridge construction . This can be becoming guiding fuctiong for the curved rigid frame bridge construction from now on .The curved rigid frame bridge's deformation is more difficult than common continous rigid frame ,because of the infection about coupled action of bending with torsion . As this question , building lots of modle , based on the model of Yin shuigou Bridge , some have different radius , some have different pier heights. And summarize the different radius and different pier heights infect the mechanical propertie for the curved rigid frame bridge through the model calculation analysisi on the most big hang stauts nad finished bridge state . Through analysis the migration phenomenon on the top of pier ,caused by the coupled action of bending with torsion, woe proposed some common rules combine with the rule data . The purpose is supported reference thoughts for the design and construction control of the curved rigid frame bridge.
