Abstract:
Aimed at the strong subjectivity and the big error of the evaluation index quantization and the weight decision of traditional decision methods, the interval hierarchy decision method was set up to optimize the soft ground improvement scheme by comprehensively applying the interval mathematics theory, the analytic hierarchy process and the interval relative analysis method. Taking a project for example, the order of the various programs was got by calculating the degree of membership. The results show that comparing with the other methods, the interval hierarchy decision can give a full consideration to the uncertainties of subjective judgement, the interval evaluation index value and the interval weight can greatly improve the decision accuracy, it provides a new method for soft ground treatment decision. 8 tabs, 1 fig, 13 refs.
