Abstract

Factors affecting liquefaction are analyzed. Qualitative factors along with liquefaction itself are conceived to be of fuzziness the common methods cannot deal with. A new method – the Multiple-Stage Multifactorial Evaluation is introduced to evaluate the liquefaction potential of sand which can take into account not only the factors considered by the common methods but also these qualitative factors which otherwise cannot be considered by the explicit mathematic evaluation methods and can treat each factor according to its importance to liquefaction. Tests with the method show a higher correct evaluation rate over other methods. Conclusion is drawn about the liquefaction potential of the upper lens in the ground of the Pubugou Power Station under an earthquake of the seventh degree.

Liquefaction Potential Prediction by Multiple Stage Multifactorial Evaluation

St. Louis, Missouri

Factors affecting liquefaction are analyzed. Qualitative factors along with liquefaction itself are conceived to be of fuzziness the common methods cannot deal with. A new method – the Multiple-Stage Multifactorial Evaluation is introduced to evaluate the liquefaction potential of sand which can take into account not only the factors considered by the common methods but also these qualitative factors which otherwise cannot be considered by the explicit mathematic evaluation methods and can treat each factor according to its importance to liquefaction. Tests with the method show a higher correct evaluation rate over other methods. Conclusion is drawn about the liquefaction potential of the upper lens in the ground of the Pubugou Power Station under an earthquake of the seventh degree.
