The friction factor of glass reinforced plastic mortar pipe and typical soil of Shanghai, the develop characters of friction and the effect of injecting slurry on the frictional characters are got through the experiments. The result shows: the ektexine of glass reinforced plastic mortar pipe is slipperier than concrete pipe; injecting slurry could minish the friction between soil and pipe, but the effect of minishing friction is bear
