| Abstract: | Using 30M pre-stressed hollow slab integral reinforcement of the super-structure of Qianjindong Large Bridge as the example,to illustrate the design and construction features of the "less girder more rid" technique with respects to the structural characteristics,workmanship and critical technique. Finally to demonstrate the successful application of the "less girder more rid" technique provides important reference to the hollow slab superstructure reinforcement by verification calculation,simulation testing,and monitoring results. |
