非饱和土水特征曲线特性研究

Research on Characteristics of Unsaturated Soil Water Characteristic Curve

在实际的工程中需要对饱和土进行实验研究,以了解其性能,然而通过使用土水特征曲线能够非常方便的对非饱和土特性进行了解,而不需要进行繁琐的实验研究。所以文章将主要对非饱和土水特征曲线进行研究。土水特征曲线会受到不同因素的影响,比如空隙结构、矿物成分和收缩率等,为了能够具体了解这些因素对曲线的影响,文章通过实验研究的方法,选择两种不同地区的土作为实验样本,然后分析各种因素下土水特征曲线的变化。最后还提出了土水特征曲线公式,虽然国内外的相关学者已经研究出较为成熟的曲线公式,但是这些公式非常复杂,在实际应用过程中比较麻烦,所以文章提出了曲线公式相对两将比较简单,虽然其精度性不高,但是具有一定的准确度。

In actual engineering,it is necessary to conduct experimental research on saturated soil to understand its performance.However,it is very convenient to understand the characteristics of unsaturated soil by using soil-water characteristic curves,without the need for tedious experimental research.Therefore,this paper will mainly study the unsaturated soil-water characteristic curve.The soil-water characteristic curve will be affected by different factors,such as void structure,mineral composition and shrinkage rate.In order to specifically understand the influence of these factors on the curve,the paper uses experimental research methods to select two different regions of soil as experimental samples,and then analyze the changes of soil-water characteristic curve under various factors.Finally,the soil-water characteristic curve formula is proposed.Although relevant scholars at home and abroad have developed more mature curve formulas,these formulas are very complicated and more troublesome in actual application.Therefore,the paper proposes that the curve formula is relatively simple.,Although its accuracy is not high,it has a certain degree of accuracy.
