摘要
预浸水是黄土力学性质研究和地基处理的一种重要手段。简要分析了进行现场浸水试验的必要性,详细评述了我国现场浸水试验的研究历史和发展现状,重点介绍了浸水试验的关键技术、湿陷变形规律和湿陷性评价等方面所取得的成果,指出了现行规范中湿陷性判定、地基处理厚度、剩余湿陷量及停水标准等方面存在的问题并给出了相应建议,最后指出了今后研究工作的主要趋势。
Pre-soaking treatment is a kind of important means on loess mechanics and foundation treatment in loess area. The necessity of in-situ soaking test is briefly analyzed. The historic development and the present researches on in-situ soaking test in China are concluded;and some comments are accordingly given. The main achievements are emphatically recommended, including key technology of soaking test, law of collapse deformation and collapsibility evaluation, etc. The main problems existing in the current criterion and some relevant suggestions are pointed out on collapsibility evaluation, the thickness of foundation treatment, remnant collapse and the standard of cutting off the water, etc. Finally, the future research trends are presented.
