Research on Key Risks of Tower Crane Based on Complex Network
Publication: ICCREM 2021
ABSTRACT
Tower crane is the key equipment at the construction site, facing complex operating environments; there are a lot of construction safety issues caused by risk coupling. From the perspective of the whole process from tower crane entering the construction site to leaving the site, based on the analysis of the accident causality theory, combined with literature research and questionnaire survey, this paper establishes a list of four types of key risks including human, machine, management, environments that tower crane faces in the three stages of installation, use, and disassembly; then the risk network model is established based on the complex network theory, to analyze the topological characteristics and key risk characteristics of the tower crane safety network. The research shows that the method reveals the evolution law and coupling relationship of the safety risk in the whole process of tower crane, realizes the quantification of key risk characteristics, and provides decision-making basis for proposing targeted control measures to slow down the risk transmission and improve risk management of tower crane.
