| 摘 要： | 采用模糊集理论，提出了一种模糊反演疏水沉降地层井筒负摩擦力的分析方法。该法考虑了反演井筒所受负摩擦力问题中的不确定性、不精确性即模糊性。给出了算例并对模糊反演负摩擦力结果进行了隶属度、敏感系数及贡献权等模糊分析。

| Abstract: | By applying theories of Fuzzy sets,proposal is offered of an analytic method of Fuzzy inversion of negative friction on shafts through de watered subsiding grounds.In the method,consideration is given of the fuzziness,that is,uncertainty and inaccuracy of the negative friction on the shaft in question.Demonstration is made of arithmetic examples and Fuzzy analysis is conducted of the results as to the degree of membership,coefficient of sensitivity and weight factor of contribution. |
