Interface Parameters

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.

Function Relationship

The incremental digital PID technology and pressure regulating technology are adopted for this thermostat. The results show that it can be better stabilize the temperature and can control the residuals between ±1 degrees Celsius. The experiment in transformation between solid and liquid of ice is designed on this basis. By changing the temperature and specific area, the law about melting time and rate between temperature and specific area is discussed and the proper empirical equations are obtained by using the MATLAB. Finally the result is that temperature and specific area can influence the process with power function relationship.
