Belong to one of the most dangerous industries , construction and security situation is very grim , and therefore improve construction site safety management to protect employees and property , is of great significance in the entire world within the construction industry . The article information entropy , hierarchical analysis , and the unascertained measure theory , and combined with the characteristics of the construction site safety management , establish unascertained measure based on the construction site safety management evaluation model . Our existing construction site safety management evaluation is not sound enough , This article established a comprehensive evaluation index system of construction site safety management , including safety management , safety management system , civilized construction site , production safety , security, education, labor protection outside subcontract management , construction conditions , construction supervision of 9 indicators , institutional and responsibilities , management by objectives , construction organization design , segment (sub- ) engineering safety technical tests, such as an evaluation of the 44 secondary indicators , this research construction site safety management evaluation , information entropy theory to calculate the two indicators of the right weight , followed by the Analytic Hierarchy Process to calculate an index weight , then take advantage of unascertained measure theory on construction site safety management evaluation index system is calculated based on unascertained measure evaluation model of construction site safety management principles of clear , simple process , operability , and dealing with uncertainty impact factors than fuzzy math less loss of information , computing simple , more practical and reliable . The evaluation results are basically consistent with the actual situation in a construction site safety management evaluation show that the model has a certain value .
