土中水的存在形式多种多样,大致可分为液态水、气态水及固态水三类。不同类型的水对土的工程特性起着不同的作用,其中较重要的是结合水、毛细水和重力水。随着我国四化建设的进程,人们对上中水,尤其是土中结合水的研究已越来越重视。众所周知,土中水分子的活动能力和结合水的 There are various forms of water in soil, which can be roughly divided into liquid water, gaseous water and solid water. Different types of water play different roles in the engineering properties of the soil, of which the most important is the combination of water, capillary water, and gravity water. With the progress of the four modernizations in China, people have paid more and more attention to the study of the upper water, especially the combined water in the soil. As we all know, the activity of water molecules in soil and the combination of water
