摘要
在专家凭经验无法准确地确定评价指标的权重时,用相似系数确定权重,给出了一种新的多指标综合评价方法.将该方法应用于膨胀土的胀缩等级分类,其合理性和有效性得到了验证.
When the expert can＇t determine the index weight by experience, this paper caculates weight of index by similar coefficient. It gives a new method multi-criteria comprehensive evaluation. The method has been applied to determine expansive scale of expansive soils and its reasonableness and effectiveness is proved by the example.
