摘要：
In order to find out the distribution law and the influence factors of dredger fill endogenous contaminants, the structural components, permeability and distribution of total nitrogen and total phosphorus of dredger fill in Tianjin artificial coastal zone were analyzed through field sampling and studied by laboratory simulation tests. The results show that the distribution of endogenous contaminants near seaward side is higher than the backward side because of the influence of the permeability change of the groundwater system, and it increases with time mainly for the reason of micro-structure change and physical and chemical action such as ion exchange and precipitation reaction. This study has a practical application value for protecting artificial coastal groundwater and seawater quality.
