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 frictionmonolithic interfacemodification factorThe objective of this study is to assess the shear friction characteristics of lightweight aggregate concrete (LWAC) prepared using artificially expanded bottom ash and dredged soil granules. A total......
3. Pipe-soil finite element model The purpose of this investigation is to determine what effect variations in pipe-soil friction coefficient would have on pipeline global stability and buckling. These include stability parameters such as the effective axial force, pipe-end expansion, number and distr...
11.8.1Soil Friction Factor Thefriction factoris defined as the ratio between the force required to move a section of pipe and the vertical contact force applied by the pipe on the seabed. This simplified model (Coulomb) is used to assess stability and requires an estimate of the friction fact...

The recorded and calculated coefficient of traction based on the summation of the force for the series of track elements were comparable, but were considerably lower than the predicted values, probably due to internal track friction rather than soil sinkage. The tractive efficiency for both a hard...
