The assessment of the damage caused by seismic liquefaction is really an uncertain problem, which not only has a random property, but also a fuzzy character. In this paper these two characters have been taken into consideration to evaluate seismic liquefaction damage at the site. The seismic liquefaction damage is treated as a fuzzy random matter to evaluate its fuzzy probability in order to get the more practical uncertain results. Finally, There are thirty liquefaction cases of Haicheng earthquake (1975) and Tangshan earthquake (1976) which have been analysed with suggested fuzzy probability. It may be seen that the results of analysis not only closely agree with facts, but also represent the numerical assessment of the degree of liquefaction damage. |
