摘要
利用淤泥质粘土掺入不同比例的粉煤灰 ,分别进行了渗透、固结、直接剪切及三轴剪切试验 ,详细研究了粘土掺入粉煤灰后其工程力学性能变化的特征以及粉煤灰加固软土的机理。试验结果证实 ,利用粉煤灰处理软土地基是一种所需投资较少且有明显效果的方法 ,并可带来良好的环境效益和社会效益。
The muddy-clayey soils was mixed with powdered fly ash in different proportion and was tested for its permeability, consolidation, direct shear, and triaxial shear strengths, respectively. The mechanism of the consolidation of soft-soil foundations powdered fly ash are studied in detail, and the change of engineering mechanical properties of the clayey soil mixed with the fly ash is elucidated in detail. The test result shows that using powdered fly ash to consolidate soft-soil foundations is inexpensive and effective.
