基于Euclid理论的震后恢复重建民用建筑工程质量评价

Quality Evaluation for Post-earthquake Civil Building Reconstruction Based on Gray Euclid Theory

为给我国震后灾区恢复重建的民用建筑工程质量评价提供一个更合理的评价标准,首先采用文献数据库和问卷调查法选取5个一级指标和23个二级指标来构建质量评价层次结构模型,然后运用区间特征根法求出各评价指标的权重。最后选择四川省芦山县某汶川地震灾后恢复重建小区作为评价对象,采用灰色相对欧几里德方法进行工程质量评价分析,计算出与不同评估等级相对应的灰色Euclid加权关联度,根据该模型虽然得出该小区重建质量为优,但是还存在一些影响工程质量的因素。该结论与恢复重建实践过程相符,说明了该指标体系具有一定的合理性,同时该模型存在一定的有效性。

In order to provide a more reasonable evaluation standard of the quality evaluation for post-earthquake civil building reconstruction,4 first grade indexes and 23 second grade indexes are firstly selected through some literature databases and questionnaire method to set up the hierarchy model of quality evaluation. Finally,a typical civil buildings reconstruction community in Lushan county of Sichuan province which are reconstructed after Wenchuan earthquake is selected as evaluation target,gray relative Euclid weighted correlation degree adapting to different rating grades. According to the model while it is concluded that the quality of reconstructed community is best,but there are some factors affecting the quality of engineering. The conclusion is consistent with the actual situation,to verify the validity of the model and indicate the reasonableness of the index system. Engineering quality evaluation and analysis are done by using grey relative Euclidean method and Grey Euclid weighted correlation degree is calculated with different assessment levels,According to the model,the reconstruction quality is excellent,but there are some factors that affect the quality of the project. This conclusion is consistent with the practice of restoration and reconstruction,which shows that the index system is reasonable,and the model has some validity.
