Safety Risk Analysis of Precast Bridge Deck Hoisting Construction Based on Structural Entropy Weight Method
Publication: ICCREM 2023
ABSTRACT
Prefabricated bridge deck panel installation is the main construction process for the upper structure of bridge engineering and also a major source of danger. A scientific and accurate analysis of the safety risks in the construction of prefabricated bridge deck panel installation is of great significance to reducing construction safety accidents. Firstly, a construction safety risk index system was constructed from the dimension of risk sources, and then the structural entropy weight method was used to rank the importance. Finally, the Longlingshan Overpass Project in Wuhan City, China, was selected as a case study. The case study showed that the machinery is the most important primary index, and the maintenance and quality of the hoisting steel wire rope were the most important secondary index. Targeted countermeasures and suggestions were also proposed in this article.
