Abstract：Combined with the construction of anchor cable on the slope of TGP’s permanent shiplock，the rockmass properties near anchor is studied after being prestressed. The changes of sonic wave velocity，elastic moduli and deformation values of rockmass near anchor are discussed，and the general regularity of rockmass properties near anchor after being prestressed is brought to light. The proposed achievement is valuable for the further research on prestress reinforcement mechanism and engineering design of anchor technology.
