| Abstract: | A Judgment\|management\|analysis model for the swell and shrink grades of expansive soil is established herein through the second development of GIS software\|MapInfo based on model of fuzzy mathematics to discriminate expansive soils. A project is calculated and analyzed with this model and the results indicated that an efficient, rapid and accurate path is provided by GIS for the discrimination of regional expansive soils with very good prospect for application. |
