Abstract

In order to improve safety performance of prefabricated construction, targeting at monitoring and early warning problems, analysis was conducted on unsafe behaviors, states and environment as well as cross correlation of these three hazard sources. Then, with unit space as research object, dynamic information of various hazard sources was extracted to construct hazard feature vector of spatial cell. Finally, a safety early warning model of spatial cells in prefabricated construction was constructed by using SVM classification algorithm. The results show that the model has good generalization ability, which can identify safety risks of space cells in practical construction sites. © 2020 China Safety Science Journal.
