The Fuzzy Seepage Theory Based on Fuzzy Structuring Element Method

Fuzzy structuring element is a new method in solving analysis express problem of fuzzy number and fuzzy value function. The paper starts with basic conception of fuzzy structuring element, introduces the method of expressing fuzzy number by fuzzy structuring element, and puts up with analysis expression of fuzzy value function, discuss the existence of fuzzy qualified differential equation and gives the express method of it’s solution. By analyzing the uncertainty of seepage rate in landfill, leads-in the conception of fuzzy seepage rate, establishes fuzzy seepage model of landfill gas migrate, obtains analysis expression of one-dimension ideal fuzzy seepage model by using of fuzzy structuring element method. This gives a new mathematical method in studying seepage problem in complex geological circumstance.
