摘要
土体填筑后,由于天气、地下水等因素的影响,填料的含水率都会发生变化,这样势必影响工程填筑体的物理、力学性质。对不同初始含水率和初始干密度的土体在浸水压缩作用下其干密度和含水率的变化进行试验,并分析研究土体含水率及其密实度的变化规律,对填筑土体工程的设计和施工提出相应建议。
The moisture content of the placed material of an earth mass changes due to influences exerted by weather, ground water and other factors after its placement, and thus both physical and mechanical properties of the embankment will certainly be affected. This paper makes an analysis and a study of the change law of percent moisture content and density of an earth mass by carrying out tests for dry density and moisture content of the earth mass with various initial moisture contents and initial dry densities after being soaked and compressed and then puts forward appropriate proposals for design and construction of earth embankments.
