1、Exercise 2: PLASTICITY OF FINE SOILSPlasticity is an important characteristic in the case of fine soils, the term plasticity describing the ability of a soil to undergo unrecoverable deformation without cracking or crumbling. In general, depending on its water content, a soil may exist in one of the
2、 liquid, plastic, semi-solid and solid states.The upper and lower limits of the range of water content over which the soil exhibits plastic behaviour are defined as the liquid limit (wL) and the plastic limit (wP), respectively. The water content range itself is defined as the plasticity index (IP),
3、 i.e.: IP =wL -wPHowever, the transitions between the different states are gradual and the liquid and plastic limits must be defined arbitrarily. The natural water content (w) of a soil relative to the liquid and plastic limits can be represented by means of the liquidity index (IL), whereIL = (w -w
4、P )/(wL -wP)The transition between the semi-solid and solid states occurs at the shrinkage limit,defined as the water content at which the volume of the soil reaches its lowest value as it dries out.Exercise 2: PLASTICITY OF FINE SOILS 翻译成中文 结合第一章专业英语的基本特点，分析短 文在语言、语法、词汇及结构上具体有什 么特点 以小组为单位抽查个人，所得分数代表小 组得分。 练习要求：
