Simulation Study of the Propagation of Underground-Construction Worker Unsafe Behavior

Abstract

The proliferation of unsafe behavior in underground-construction sites has been widespread, which leads to accidents in underground construction from time to time. Accidents are not only a threat to the personal safety of construction workers but also cause property losses. Intervention on how to prevent the propagation of unsafe behavior among underground-construction workers in a timely manner, further improvement in the safety-management level of construction enterprises, and ensuring smooth implementation of projects are urgent measures to solve this problem. In this study, an SCIMR (Susceptible-Contacted-Infective-Removed) model was developed to study the spread of unsafe behavior among underground-construction workers. Increase in the improvement, control, and awareness rates could provide a preventive effect on the spread of unsafe behavior among underground-construction workers, whereas increase in the adoption and forgetfulness rates could facilitate increase in unsafe behavior. This work combined the SIR (Susceptible-Infective-Removed) theory with the underground-construction context to enrich the theory of underground-construction safety personnel management, which provides a reference solution and suggestions for construction companies to intervene and predict the proliferation of unsafe behavior and a novel method of planning and direction for safety management.
