The Related Research about the Thickness of Covered Soil in Reclaimed Land Filled by Fly Ash

Abstract

Exploring the best mode of fly ash reclamation by the tests of water content, water retention curve, PH value, monitoring of wheat growing and wheat yield in different conditions of covered soil’s thickness. The results show that if the thickness of the covered soil’s layer between 24cm to 40cm,the covered soil has the best ability of water saving and supplying, the lowest cost for reclamation and the highest yield, so we can get the best benefit.
