Abstract
In this paper, according to the principle of fuzzy mathematics, five principal factors are considered, earthquake intensity I, the thickness of overburden 1Ryer of non-liquefacted cohesive soil Ho, SPT blow count (China) N, the depth of point of SPT ds, and groundwater level dw, at the same time, the subordinate functions of them are estab1ished. The rank of liquefaction is classified into four sorts: non-liquefaction, probable-non-liquefaction, probable-liquefaction and liquefaction. The fuzzy multifactorial evaluation is presented for predicting site earthquake liquefaction of sandy soil, and the operation of M (.,+)is applied to calculation of fuzzy matrix. At last, a comparison between the results of predicting with the procedure and the fact of the cases of Haicheng and Tangshan earthquake, the effects are satisfactory.
