摘要
砂性土的液化问题比较复杂,且在影响砂性土液化性能的各种因素之间存在一定的模糊性。基于模糊数学原理,选取地震烈度、标贯击数、平均粒径、粘粒含量、不均匀系数和有效上覆应力等主要影响因素指标,建立砂性土液化性能的模糊评判模型,针对某工程砂性土地基进行液化评价,可供其他类似工程参考。
Based on the complexity of sand soil liquefaction and the fuzziness among the influencing factors of sand soil liquefaction performance, we apply fuzzy mathematic principle for selecting earthquake intensity, SPT number, average grain size, clay content, non-uniformity coefficient and effective overlying stress and other influencing indices. In addition, we establish a fuzzy evaluation model for sand soil liquefaction performance and make liquefaction evaluation of sand soil foundation, which will provide references for similar projects.
