%X <p>Treatment scheme of soft soil foundation in highways is one of the key factors influencing project quality, project cost and construction period. In order to present treatment schemes of soft foundation which are reliable, economic, safe and suitable, we introduce variation coefficient which is a kind of statistical parameter that can reflect characteristics of attributes to calculate weight of attribute parameters. In association with variable weight, we propose an intelligent evaluation method using case-based reasoning. Through a lot of examples of the soft soil treatment in foundation projects which have clear conclusions, we established a database of treatment scheme for soft soil foundation. Then, the similarity between the target case and source case is calculated by using Euclidean Metric Distance formula. At last, we find the source case which is the most similar to the target case. The results of case study show that, on the basis of variable weight, the intelligent evaluation method using case-based reasoning for soft foundation treatment of expressways is reliable, and the research results will provide a scientific and reasonable basis for soft foundation treatment.</p>
