Research on Construction Technology of Mid-span Closure of Continuous Rigid Frame Bridge with High Pier and Long Span:Taking Lugou River Bridge as an Example
In the construction of high pier long span continuous rigid frame bridge,the middle span closure is an important step in bridge construction.Taking Lugou River Extra-large Bridge as an example,aiming at the characteristics of site construction,the specific operation of closure weight,jacking and other important links are studied and analyzed in detail.The weight and position of closure weight are calculated,and the core data such as the size of jacking force are determined by using Midas 2022 software,so as to ensure the smooth completion of bridge closure.
