The technology of Reinforced soil has been widely used in civil engineering, its theory has some development . However, there is nearly any study about the theory of Geogrid-reinforced fly ash .In this paper, study the interface characteristics between fly ash and geogrid through the pull-out test,reach the following conclusions:the size of normal stress and water impact the interface parameters between the geogrid and fly ash;the interface friction coefficient between Geogrid and fly ash is small,adding gravel to fly ash can improve the interface friction coefficient between geogrid and fly ash.

In this paper, the mechanical property experiments of concrete based on the seawater and sea sand have been carried in different raw materials preparation and different conservation environments. The results show that the early strength and late strength of concrete based on seawater and sea sand are better than concrete based on freshwater and sand. There is no significant strength decreased for concrete based on seawater and sea sand under accelerated alternating wet and dry conditions. For concrete based on seawater and sea sand mixed with admixture, the downward trend of late strength is significantly delayed, the late strength of concrete based on the seawater and sea sand mixed with slag gets the most obvious growth trend, while the late strength of seawater and sea sand concrete mixed with fly ash gets the largest increment.
