Preliminary Study on Rainfall Infiltration of a Homogeneous SAP-Enhanced Cover

In order to improve the anti-seepage performance of cover, this paper proposed use super absorbent polymer (SAP) particles water storage capacity soil, and mixed them into soil build an SAP composite but law movement in which is not clear. paper, a series column model tests were carried out measure changes pore pressure volume content cover at different depths. The results showed that under extreme rainfall condition once-in-a-century Nanjing, infiltration amount was only 12.7 ml, while homogeneous sandy 2510 indicating good.
