Abstract

At present, the safety evaluation of long-span bridges in construction is a hot research topic in the world. Considering the main factors (cantilever erection, wind load and temperature change), which influence the change of bridge member stress during the construction phase, the reliability of construction stage of the bridge is analyzed by simulation. Then the reliability value of the main arch root of the bridge main span under the most unfavorable load condition is acquired, and the optimal internal force state is determined when the closure construction of the bridge is finished.
