摘要
本文根据Darcy定律定义了渗透系数,提出了多孔混凝土满足Darcy定律的合理的水力梯度。利用国外的试验仪器,根据其试验方法来测定不同空隙率下的多孔混凝土的渗透系数。最后,讨论了有效空隙率和空隙率对多孔混凝土排水性能的影响。
In this paper, the permeability coefficient is defined according to the law of Darcy, and the reasonable hydraulic gradient meeting the laws of Darcy is put forward for porous concrete. Besides, the permeability coefficient of porous concrete with different porosity is measured with foreign equipment and foreign test method. Finally, the influence of effective porosity and porosity on the performance of the porous concrete drainage is discussed.
