摘      要：The present paper discusses the effects of small plants on the dump mass reinforcement and slope *** roots of smaller plants(such as grasses and shrubs)do not go ***,they stabilize the slope by binding the upper layer of dump *** strength of the dump mass with and without root reinforcement is determined by laboratory shear box *** increased cohesion(apparent cohesion)of upper layer of the dump mass due to plants is determined by fabricated shear *** kinetic behavior of the dump has been investigated using the FLAC *** factor of safety has been calculated in order to determine the possible effect of small plants on the stability of the dump *** is observed that the small plants do not significantly improve the factor of safety(FOS)of ***,it could be useful for early *** grasses quickly bind the upper surface,whereas shrubs too immensely strengthen the stability of the dump in the initial stage.
