| Abstract: | Based on practical construction of Baoji-Hanzhong Expressway, the paper introduces the construction technique of both-halves synchronized pushing and closure of large-span continuous rigid frame girder of Wulipo Extra Large Bridge called ＂Top 1 High Pier in Northwest China＂ with closure sequence adjustment under unfavorable condition of high temperature. It turns out that not only the requirements of bridge structural design is met, but also the construetion period is guaranteed. |
