| The construction industry is one of high-risk industries,construction process safety management is an important element of the construction industry,and the safety evaluation of safety management has been a major concern for people.Construction site safety purpose of the evaluation is to implement the "safety first,prevention first" principle.Safety management in the prophylaxis into autonomous control,and improving accident prevention capabilities.Aiming at the complexity of the safety evaluation system in construction building sites,extension superiority evaluation method is used in safety evaluation system of construction building sites.According to the matter-element and extension theory,the model of extension superiority evaluation method in safety of construction building sites is built and the information entropy has been applied to determine the weight of each factor.According the optimal ordering,analysis of the construction site safety grade.Then take a application as an example,the correctness and applicability of the evaluation is tested and verified.we can found that evaluation method can meet the construction site safety evaluation requirements,which can provide the basis for the construction evaluation and guide to develop a reasonable basic precautions for the construction site. |
