震后房屋评价模型的改进
|
摘要
科学的评定震后的已损毁建筑对震后房屋处理,城市功能的及时恢复,社会生产稳定、生活秩序的恢复等,具有重要的现实意义.针对传统震后的损毁房屋评价模型的不足,提出了一种震后房屋危险性鉴定的评价模型,结合AHP方法,利用实际中各种因素影响的权重构建了相应的模糊隶属度函数,计算地震损毁房屋的等级.利用真实地震中的房屋数据对该方法进行了测试和分析,实验结果表明该方法是科学、有效的,可以一定程度提高震后房屋鉴定的准确性和合理性.
Scientific assessment of damaged buildings after earthquake is very important to the building processing,the timely restoration of urban functions,stability of social production and living order of restoration.In this paper,after analyzed the traditional evaluation model of the earthquake damaged housing,presents a risk assessment identification model for housing after earthquake,combined with AHP method,using the actual impact of various factors in the weights of the corresponding construct fuzzy function,calculate the level of earthquake damage to building.In this paper,the real earthquake of building data test this method,experimental results indicate that this method is scientific and effectively,improve the identification accurate and rationality.
