Abstract


Basis the cable saddle without pre- bias construction of the suspension bridge construction sequence , the main content of the Lancang River suspension bridge superstructure construction control study was to investigate , and to be applied in engineering practice . Linear adjustment for the Ji Zhunsuo Share erection during use of the analytic iterative method for linear adjustment , given operable Adjustment Cable . Based on the basic theory of gray system , in the main cable erection period , in the use of the sensor temperature measurement errors caused by wire length correction ; in stiffening girder hoisting construction period , according to the construction characteristics of the Lancang River suspension bridge , application of gray system theory, the use of the construction phase of the main tower deviation of the measured data , multi-step prediction of the main tower deviation better grasp the correction tension opportunity to guide the construction . This article also strain meter stress measurement in concrete structures commonly used in embedded steel strings , improved analysis of the main tower of concrete Sarasota contraction , creep effective way to provide a reliable guarantee for the Sarasota real stress .
