Study on Construction Safety of Management System Based of Extension Theory

Safety is the most important problem to construction enterprises,and the influential factors about safety are too many and complicated.Considering that current safety management evaluation methods are hard to make a prompt and systematic judgment of construction safety problems,extension theory is used to study safety management system of construction enterprises in this paper.Firstly,based on the construction safety inspection standards issued by state and referring to the experience of construction safety inspection,safety levels of construction safety management are divided into four grades: safe,safe basically,unsafe and seriously unsafe.Thus,an evaluation and forewarning system for construction safety management is initially established based on extension theory,through making corresponding program,the evaluation and fore-warning are achieved.At last,this system is verified by an actual project,and the results show that this method is of practicability and effectiveness,and can be used as references for enterprise safety management.
