【摘要】 鉴于软基处理方案评价中各指标的不确定性和模糊性,将熵权理论与模糊物元相结合,建立了基于熵权的模糊物元模型.用信息熵所反映数据本身的效用值计算指标的权重,避免了权重分配困难的问题.将该模型应用于高速公路软基处理方案的评价中,得到最合理的处理方案,为选择软基处理方案提供了新途径.更多还原

【Abstract】 In view of the uncertainty of index for evaluating soft ground improvement programs the entropy value theory is applied to combine with fuzzy matter-element method to establish fuzzy matter-element model based on entropy value theory.The weights are calculated by information entropy indicating the availing value of data,and the problem of weight allocation is solved.The model is applied for programs evaluation of improving expressway soft ground and a reasonable program is got,which provides a new way to select programs for improving soft ground.更多还原
