A method of greening rock surface by artificially improving the roughness of rock surface to improve its bearing capacity of soil,combined with the guest soil spraying technology,is proposed.Firstly,on the basis of studying the fluidity of mud,the measurement method of rock surface bearing capacity of soil is established.Then the rock surface is transformed by cement mortar leveling,cement mor-tar micro step and orange rod cement mortar micro step methods,and the bearing capacity of the soil for transformed rock surface is stud-ied.The results show that the coating of cement mortar improves the bearing capacity of soil due to the improvement of rock surface rough-ness,and the micro step of cement mortar provides conditions for bearing soil due to the change of rock surface shape,so the bearing ca-pacity of soil is greatly improved.The micro step of straw rod cement mortar not only retains the advantages of micro step of cement mor-tar,but also forms sharp protrusions due to the addition of straw rod,it can retain leaves and weeds,so as to further improve the ability of rock surface to maintain soil,water and fertility.Finally,the concept of standard soil bearing capacity is proposed,which solves the prob-lem of different test results of different concentrations of mud.
