| Abstract: | A fuzzy comprehensive evaluation method for evaluating the foundation stability of new buildings above work-out areas was proposed on the basis of the theory of fuzzy mathematics. A lot of factors that influence foundation stability were analyzed,and the evaluation elements were determined. A method for determining the subjection degree of primary factors was presented. The analytic hierarchy process was used to determine a judgment matrix,which distributes weight coefficients for every factor rationally. B... |
