EXTENICS BASED GRADE SYSTEM FOR EXPANSIVE SOILS AT JING MEN POWER PLANT AREA

Using the method of extenics,a grade system for expansive soils is developed.The expansive soil at Jingmeng power plant area is examined with the method of extenics.By constriction,the estimated result is compared well with the result from the analytical method of grading distortion in the criterion.the result shows the extenics based grade system is applicable.
