Conclusions
-
1.
A relation was obtained which permits determining the coefficient of friction of cohesionless soils on watertight polymer film facings of earth structures at preliminary design stages.
-
2.
At present it is recommended to determine the coefficient of friction of soil on film experimentally on single-shear type instruments. The use of the existing instruments with a tiltable platform for these purposes requires additional substantiation owing to the possibility of errors.
-
3.
A further experimental study of this problem is needed for obtaining sufficiently reliable shear characteristics.
