Abstract In this paper the liquefaction of sand is discussed based on catastrophe theory，which reflects the discontinuous changes during some physical progress. A catastrophe model on the liquefaction of saturated sand is set up with the analysis method of liquefaction safety factor of sand，and a series of cases for the liquefaction of sand are estimated by the measured data. The results calculated by catastrophe theory model are in agreement with practical facts. The application of catastrophe theory to the liquefaction analysis of saturated sands is efficient and feasible.
