摘要
提出了利用土的密度、液限、塑限、液性指数、塑性指数和自由膨胀率等6项指标来判别南宁膨胀土胀缩性等级的模糊数学定量评判方法,对6项指标与胀缩总率进行了相关关系分析,用其相关系数来确定相应的权重值,建立了相应的模糊数学评判模型,并用实例对所建的模糊数学评判模型进行了验证,其结果与实测结果相吻合。
Based on six properties such as density, liquid limit, plastic limit, liquidity index, plasticity index, and free swell rate, this paper presents quantitative fuzzy evaluation of swell-shrinking degree of swelling soil in Nanning. Through the analyses on the correlativity of the properties and total swell-shrinking rate, a model is established and validated with field measurements.
