摘　　要：基于熵理论,把深基坑坑壁支护方案多目标决策问题中的固有信息与决策者经验判断的主观信息进行量化与综合,建立了基于熵权的坑壁支护方案优选的多目标评价模型,并通过实例计算,说明该模型结构严谨,物理意义明确,决策结果更加合理,符合实际。Based on the entropy, the objective information and subjective information of the multiobject decision-making on deep-foundation side-wall supporting solution are quantified and integrated, then the multi-object model to evaluate the side-wall supporting solution according to entropy-weight is set up. Through examples it is proved that this model is precise in structure ,ex act in physical definition,more reliable and reasonable in decisionmaking.

关 键 词：坑壁支护 优序评价 熵权
