Safety Evaluation Study for Construction Projects Based on Accident-reason Theory

Building construction is a field in which accidents occur frequently.Based on the characteristics of building construction,this paper studies in detail the safety evaluation problems of construction by the accident-reason theory and system block diagram analysis method.First,the safety evaluation index system for construction projects are established.Then,the weight values of per evaluation index for the safety evaluation system can be obtained.In the end,by using one instance,the safety of construction project can be effective evaluated.
