- Abstract
According to the fuzzy and uncertainty characteristics of soil liquefaction, a comprehensive fuzzy evaluation model of soil liquefaction is presented. In the comprehensive fuzzy evaluation model of soil liquefaction, the following factors, such as earthquake intensity, SPT counts, groundwater level and mean diameter of sand soil particle which affect the liquefaction of sand soil were considered, and the sketch map of trapezoid subordinate function was adopted and the subordinate function expression of each factor was given. The results show that the comprehensive fuzzy evaluation model of soil liquefaction is feasible and valuable.
