Article Preview

Based on the integral synchronous lifting project of main span for Nanlin Bridge, this paper mainly studies the causes which lead to difference of non-uniform displacement in the key parts of the lifting bridge and its impact to construction safety and calculates the maximum limit value of displacement difference. A displacement sensor network is applied to monitor the difference of non-uniform displacement, a posture adjustment and control algorithm based on average displacement is proposed to ensure construction safety during the synchronous lifting. The numerical simulation of synchronous lifting of Nanlin Bridge is conducted to verify the validity of posture adjustment and control algorithm, this paper provides important theoretical basis for the promotion and application of these results in practical projects.
