摘　　要：传统的权重确定是依据专家经验,它在一定程度上反映了实际情况,但也存在着可能会偏离客观实际且难于定量表示等问题。针对传统权重确定法的缺陷,提出了一种新的权重确定方法,即用层次分析法来确定隧道病害分级时各影响因素的权重。通过工程实例的验证,进一步证明了此法的科学性。The traditional method of determining the weight is based on the experts experience. Although some facts are manifested, issues, such as inaccurate data and difficulty to quantitative analysis, come into being. So a new method determining the weight by the AHP technique is put forward in this paper. After testified in a practice, the new method is recognized.
