Abstract Geotubes are heterogeneous structures composed of filling sand and
bag material, and its permeability characteristics are different from that of filling
sand. The uncertainty of geotubes permeability characteristics results in the failure
of seepage analysis of geotube dams, which restricts the safety assessment of the
dams. As the basis of the study on the seepage mechanism of the geotubes, the
influence of particle grading on permeability coefficient of filling sand and sand
covered with geotextiles were explored by the permeability tests of filling sand
with different particle grading under the condition of sand covered with… More >
