堤坝下软土夹层地基塑流失稳的模糊综合评判

Fuzzy comprehensive evaluation on the unstability caused by plastic flow of the ground with soft stratum under embankment

将模糊数学的综合评判方法引用到堤、坝下软土夹层地基塑流失稳的分析中。构造了各因素对应的隶属函数,建立了评判矩阵,拟定了相应的权重,运用M(·,+)数学模型进行模糊矩阵运算。最后对堤坝下软土夹层地基塑流失稳做了最终评判。

In this paper the authors quote the method of fuzzy comprehensive evaluation to analyze the ground under embankment for the unstability caused by plastic flow of the soft stratum. They establish subordinate function and evaluation matrix. The authors work out the corresponding weight, calculate the fuzzy matrix using the mathematical model M (·, +), and evaluate the unstability caused by plastic flow of the soft stratum of the foundation under embankment.
