This.paper pres.nts.an analytical approach for es.imating frictional res.s.ance to pipe movement at s.il and external pipe s.rface of buried coated pres.urized s.eel pipes.relative to the internal thrus. *** propos.d analytical method was.developed bas.d on 36 experiments.which involved three coating types.cement mortar(CM),polyurethane type-I(PT-I),prefabricated plas.ic tape(PPT))on pipes.s.rfaces.three different s.ils.pea-gravel(PG),s.nd(s.,s.lty-clay(s.)),and four s.mulated over burden depths.above the pipe’s.*** s.owed frictional res.s.ance decreas.d with increas.ng over burden depth above the pipe’s.*** degree of frictional res.s.ance at the pipe-s.il interface was.found to be in the order of PG>s.>s.for all coating variations.and overburden *** coated pipe buried in all three types.of s.il produced s.gnificantly higher frictional res.s.ance as.compared to other coating *** on experimental data,the developed analytical introduced a dimens.onles. factor“Z”,which included effects.of types.of coatings.s.il,and overburden depths.for s.mplified rapid *** s.owed that the method provided a better prediction of frictional res.s.ance forces.in comparis.n to previous.analytical methods.which were barely clos. in predicting friction res.s.ance for different coating variations.s.il types.and overburden *** res.s.ance force values.reported herein could be cons.dered cons.rvative.
