土壤是岩石经一度或数度风化所形成的土粒、水份和其他杂质的混合物。它是一种极复杂的物质,其性质随土粒、杂质的大小、成份、形态以及水份的多寡而改变。认识土壤的性质是一个很困难的问题。虽然人类很早就把土壤当作工程材料使用,但对土壤的工程特性的了解却远不如对其他工程材料那样广泛和确切。直到最近几十年来,由于在土木、建筑、水利等工程上地基处理经验的累积和理论研究的发展,已有可能通过土壤试验,来认识土壤的各种工程特性,进而应用到设计工作上去。并且当土壤承载力或耐水性不符合工程需要的时候,根据土力学、土质学以及研究土壤天然膠结过程的科学成就,可
Soil is a mixture of soil particles, moisture, and other impurities formed by the rock once or several times weathering. It is a very complex substance whose properties change with the size, composition, and morphology of soil particles, and the amount of water. Understanding the nature of the soil is a difficult problem. Although humans have long used soil as an engineering material, their understanding of the engineering properties of soil is far less extensive and precise than that of other engineering materials. Until recent decades, due to the accumulation of experience in ground treatment in civil engineering, construction, and water conservancy projects and the development of theoretical research, it has been possible to identify various engineering characteristics of soil through soil tests and apply it to design work. And when the soil carrying capacity or water resistance does not meet the needs of the project, according to the scientific achievements of soil mechanics, geotechnical studies, and research on the natural cementation process of the soil,
