| 摘 要： | 膨胀土的膨胀潜势大小受很多因素的影响,并非用某一种指标可以确定,既使采用多项指标确定,也常常遇到各种指标实测值不落在膨胀潜势的同一级别里,可能造成误判.本文把膨胀土视为灰色系统,应用灰色聚类法评判陕南膨胀土的膨胀潜势等级,其结果较为合理、准确.

| Abstract: | The swelling potential of expansive soil is affected by many factors. Only one index can't determine it . All sorts of practical indexes are usually not included in the same swelling potential grades even if varied indexes were adopted. That may induce a false judgment. Regarding the system of expansive soil as a grey system,in this paper the authors demonstrate the rationality and validity of the determination of the swelling-shrinkage grades in light of the system theory. |
