A Self-anchored Suspension Bridges Construction Monitoring

Modern structure analysis theory and construction means Progress cause to developmentgreatly of the big suspension bridge，with the bridge span is increasing, making controlcalculations become an essential part of the construction. Empty cable shaped not only is thecore content of the construction control of suspension bridge, but also is the main content ofthe construction control calculations. With the suspension of the calculation of theoreticaldevelopment of large-span suspension bridge is also growing, from the original theory ofelasticity gradually developed to a limited displacement theoryThe calculated results arebecome more accurate.Utilizing the powerful computing function of the computer, and combined with thetheory of system perfecting,make construct control calculating more accurate and swifter.Atpresent，home and abroad suspension bridge construction control system is the use of some ofthe existing structural analysis software，simulation the construction process by the software，structural analysis calculated the amount of pre-partial, longitudinal displacement of the maincable saddles and other control parameters, the implementation of construction controlthrough the control parameters.This text combine the LieDe bridge construct control project practice，elaborate theimportant meaning of construetion control in construction process.
