针对进气值较低的材料提出了一种量测进气值的新方法 ,并用该法和常规的常水头渗透试验测定了 6种不同砂粒径、不同配合比的多孔砂浆块的进气值和渗透系数 .率定试验结果表明 ,多孔砂浆块比高进气值陶土板更适宜于作为裂隙非饱和渗流试验和驱替试验中的毛细隔栅 .率定结果也为裂隙非饱和渗流试验选取合适的多孔砂浆块作为毛细隔栅提供了依据 .通过对上述多孔砂浆块进气值的测定可看出 ,本文量测进气值的方法用于测定低进气值材料的进气值是简单易行的 .
A new method for measuring the air intake value is proposed for the material with lower air intake value. The air inlet of the porous mortar block with different sand particle sizes and different proportions is measured by this method and the conventional constant head penetration test The results of rate test show that the porous mortar block is more suitable than the capillary plate with high aerated value in the unsaturated seepage test and displacement test of fractures.The calibration result is also the fractured unsaturated seepage test Select the appropriate porous mortar block as a capillary grille provides a basis for the porous mortar block by measuring the value of intake can be seen in this article to measure the intake value of the method used to determine the intake value of low intake value of the material is Simple and easy.
