黄土场地自重湿陷敏感性的模糊综合评判

A Fuzzy Synthetic Judgement for Sensitivity to Self-Subsidence of Loess Foundation

本文采用模糊数学方法,对自重湿陷性黄土场地的自重湿陷敏感性进行综合评判,提出了相应的评判指标β和分档标准。计算中仅需四个数据,运算较简便,已通过12个实例验证,证明其可靠度达90%。

In this paper, by using fuzzy mathematics, a synthetic judgement for sensitivity toself-subsidence of self-subsiding loess foundation is given and a corresponding index βas well as the sensitivity criterion are also proposed. In calculation, only the depth and thegeologic age of the uppermost self-subsiding loess stratum, the distribution of self-sub-siding loess strata along the depth and the calculated self-weight subsidence areneeded. This method is easy and through the application of this method to 12 loesssites, it is seen that the relability of the method is up to 90%.
