摘要
通过模型试验观察筒形基础沉降就位后,筒内水膜形成的机理,提出了向筒内灌浆解决水膜的方案。试验通过配土、设计模型筒基、负压沉贯和筒内灌浆等操作过程,并运用正交方法进行泥浆配比,从土体破坏的角度,对筒基空载与加载不同情况下水膜高度的变化规律进行分析。
A test is designed to simulate the formation of the water layer and evaluate the feasibility of the grouting method. By means of making up soils, designing the bucket foundation models, suction penetration and grouting inside bucket, from the viewpoint of damage of soil body, the text analyses the chan ging principle of the height of water layer between load and the opposite situation. Meanwhile ,it uses orthogonal experimental design way to design the grout so that it can make the experiment more reasonable and more scientific.
