Abstract：The uniaxial compression tests are conducted on geomembrane bag with different compactness to obtain stress-strain curves and uniaxial compressive strength，and the failure pattem under uniaxial compression is discussed. The study indicates that the uniaxial compressive strength decreases with compactness increases. The 80%–85% compactness is adequate. Uniaxial compressive strength of geomembrane bag with sand is much larger than that of sand，which is 1 MPa with nearly 100% compactness，and the corresponding with sand ultimate load height is about 50 m. With the compactness decreases，the uniaxial compressive strength of geomembrane bag increases obviously，and the stress-strain curves are different.
