Program evaluation of expressway soft foundation treatment based on and fuzzy theory
Hongying Fan, Xuesen She · 2011
The grey theory and fuzzy theory combined assessment decision model were constructed for shan-meng expressway soft foundation treatment based on the grey theory and fuzzy theory, which considers the uncertain and fuzzy character of engineering geology, engineering cost, construction technique, effect of improvement and engineering reliability. The weights of affecting factor are calculated by improved analytic hierarchy process, so the accuracy of appraise is advanced. The optimal scheme choice was made according to one soft foundation section of the expressway which has four kinds of improvement programs used the decision model.
