Soils are extremely variable position, and it was this heterogeneity that long discouraged scientific studies of these deposits. 它包括三种成分:固体矿物质,水以及空气和其他气体。土质组成变化很大,正是这种不均质性大大地阻碍了科学家对这些沉积物的研究。土木工程专业英语 Gradually, the investigation of failures of retaining walls, foundations, embankments, pavements, and other structures resulted in a body of knowledge concerning the nature of soils and their behaviour sufficient to give rise to soil mechanics as a branch of engineering science. 渐渐地,对挡土墙,基础,护堤,人行道和其他结构的事故的调查发现其原因涉及到许多天然土的知识并且它们的工况充分提高了土力学作为工程科学的一个分支。土木工程专业英语 Little progress was made in dealing with soil problems on a scientific basis until the latter half of the 18th century
