摘　　要：结合在三峡永久船闸边坡的锚索施工,进行了锚索加固对周边岩体力学性状的影响的研究。重点介绍了锚索张拉前后岩体的波速、变形以及弹性模量的变化,揭示了预应力锚固改善周边岩体力学性状的规律。该成果对分析预应力锚索加固作用机理和改进预应力锚固工程设计有重要作用。Combined with the construction of anchor cable on the slope of TGP抯 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.
