类岩石锚固体声波波速与其强度特性的研究较少，针对类岩石锚固体试样制作的特殊性，结合室内单轴压缩试验，利用声波测试技术分析类岩石锚固体单轴抗压强度与声波波速的关系特点。无论标准试样有无锚固或相似原料配比变化，纵波波速增大，单轴抗压强度也相应随着增大。锚杆轴向布置和横向布置均能提高试样的单轴抗压强度，但提高的幅度很相近，这可以通过两种加锚方向的试样纵波波速变化不大来反映。对比类岩石锚固体试样单轴抗压强度随试样密度和纵波波速的变化关系，纵波波速的影响更显著。

There is less research on the acoustic velocity and strength characteristics of rock -like anchorage body.Aiming at the particularity of the rock -like anchorage sample,the relationship between the uniaxial compressive strength and acoustic velocity of the rock -like anchorage body are discussed by means of the acoustic testing technique combined with the uniaxial compression experiments.No matter its anchorage or its similarity material proportion,the longitudinal wave velocity of the standard sample increases corresponding with the increase of its uniaxial compressive strength.Both the axial arrangement and the cross arrangement of bolt can increase the uniaxial compressive strength of the sample,but all the increase amplitudes are very close,which can also be reflected by the slight change of longitudinal wave velocity under different anchorage.Compared with the change of uniaxial compressive strength along with the sample density and the longitudinal wave velocity,the influence of the latter is more significant.
