Application of Geosynthetics in Embankment Dam

As a new type of impermeable material,geomembrane and composite geotechnical membrane has in water conservancy engineering has been widely used.But in earth rock dams in the application process there are still some problems need to be studied and solved.This paper draws on the research situation at home and abroad geotechnical synthetic materials,analysis of the properties and characteristics of the geomembrane and composite geotechnical membrane,analyzes the problems existing in the application process,and the development trend in the future was prospected.
