Abstract:

Article Preview

The construction scheme of long-span V-shape rigid frame composite arch bridge is discussed. In process of simulation calculation of the construction, the author compiles APDL command flow program by using the unit birth-death technique, establishes simulation calculation model in the construction process. The creep characteristics of concrete are also taken into account. The whole process of beam first-to-arch later stage construction are calculated and studied.By researching on construction control of Xiaolan channel super large bridge, the feasibility of the construction program is evaluated, the alignment and displacement in each construction ideal state are determined and the alignment and displacement in the following construction state are predicted. The stress controling results of the critical sections are researched on to make the construction go along well as designed, make sure the safety during construction, the structural internal force under constant load and structural alignment are complied with the design requirements and the construction quality and safety are ensured.
