Research on the Construction Safety Accident Analysis Model of Deep Excavation Project Caused by Rainstorm
Publication: ICCREM 2022
ABSTRACT
The deep excavation construction project becomes more vulnerable to storm disasters along with the tendency of its large scale, longer construction period, and complex process. This paper is aimed at revealing the mechanism of the construction safety accident caused by rainstorm. Firstly, the key factors of the safe construction of excavation project are systematically analyzed. Secondly, the system dynamics model is established based on six subsystems, which are workers, project entity, rescue equipment, adjacent environment, safety protection facilities, and rainstorm intensity. Thirdly, the key safety variables, accident causal chain, and safety risk coupling relationship was identified and analyzed while the model is solved by intelligent algorithm. Lastly, the typical projects are selected for empirical analysis, and the calculation results show that the model can well simulate and analyze the evolution mechanism of the construction accidents and can provide reference for the safety prevention measures of deep excavation in rainstorm weather.
