| The construction industry is an important economic pillar of our country and has created tremendous wealth for the country and people.But at the same time,safety accidents always occur with the construction process.In order to reduce accidents and losses,it is particularly important to establish a scientific,objective and effective safety evaluation mechanism.This paper applies attribute recognition theory to building safety evaluation system,establishes a comprehensive evaluation model,and applies it to ancient Gudian's engineering case for safety evaluation.Firstly,the evaluation index system was determined by referring to relevant standards and literatures and combining with the characteristics of The ancient Dian project.Based on the traditional building safety evaluation system,attribute analysis,attribute measure,attribute identification and scoring criteria of attribute identification theory are introduced to establish the comprehensive evaluation model of attribute identification.Then,the traditional safety evaluation model and attribute recognition safety comprehensive evaluation model are applied to The ancient Dian engineering building safety evaluation.Organize experts to check and score the evaluation system indicators;determine the discriminant attributes and attribute measures through attribute recognition analysis;determine the weight of indicators at all levels by using analytic hierarchy process;determine the comprehensive attributes by combining attribute measures and weights of indicators at all levels;conduct comprehensive evaluation through attribute recognition discriminant principles and scoring principles to determine the safety grade and comprehensive score of the evaluation object.Finally,the evaluation process and results of the two evaluation methods are analyzed and discussed.The results show that it is feasible to apply the comprehensive evaluation model of attribute recognition to the safety evaluation of building engineering projects. |
