摘　　要：针对传统的加固方案评价指标的权重相对固定,不能随情况变化而灵活变动的缺点,用熵值法对初步给定的评价指标权重进行调整,做到静态赋权与动态赋权相结合,从而增强了评价的合理性和科学性。应用实例表明,调整后的权重能更准确地反映被评价方案的实际情况,为既有建筑加固方案的选择提供了依据。The weights of evaluation indicators in traditional optimization of strengthening scheme are relatively fixed,and can not be changed flexibly as the situation changes.To solve this problem,an entropy method is used to adjust the preliminary weights of evaluation indicators.Based on the method,the weights can be given both statically and dynamically,and the evaluation can be more rational and scientific.An example application of this method is presented,which indicates that the adjusted weights can reflect the actual situation of the evaluated program more accurately,and provides a basis for optimum selection of strengthening scheme for existing structures.
