According to the requirement of the devlopment of the present situation and the crisis that the agricultare of Guangdong is confronted with,this paper makes clear that the soil-fertilizer work is still very important to tire agricultural production in future,and it must be strengthened.

This paper states some treatment methods and relevant precautions of groundwater in earthwork construction.

According to the project purpose classification cupability target of earth and the mechanism to densification earth in earthpower science,this paper briefly discusses that the earth hydrous ratio densification function and drought density are taken as the importance of quality control earthwork principle in thedike earthwork construction.

Taking earthwork construction of a power plant soft soil foundation as a example,it introduces earthwork constructing method and announcements of soft soil foundation,and summarizes its constructing experience,practice proves that formulating scientific and rational constructing scheme is a reliable way of safely high quality finishing engineering item.

Mechanization of earth work construction machinery;

This article expressed the requirement,the test objects,the test standard,and the test method of the fill materials for the earth work,and show the differences from China.
