中文摘要：
为了研究原始岩石试样的动态力学特性以及分析试样内部节理裂隙分布情况，首先通过理论分析，给出用纵波波速和横波波速表示的岩石的各种动态参数的表达式。应用全波形声发射仪搭建试验系统，将原始岩样沿长度方向等分为不同的分段，测定不同分段的纵波速度，依据纵横波速之间的关系求出横渡速度，从而得到岩样沿长度方向不同分段的各种动态参数．根据这些参数的变化，定性讨论岩样沿长度方向的强度变化，以及内部的损伤变化情况。
英文摘要：
Abstract： This paper studied the dynamic mechanical charac- teristics and the internal jointed distribution situation of the original rock sample. Firstly, expressions of different dy namic parameters were presented by p wave and s-wave ve locity through theoretical analysis. The test system was built by full waveform acoustic emission instrument, and the orig- inal rock sample was divided into different segments along the length direction so as to determine different p-wave ve- locity in each segment. Then based on the relationship be tween the velocity of p-wave and s-wave, s-wave velocity and various dynamic parameters of different segments along the length direction could be found. According to the changes ofthese parameters, the intensity changes along lhe lenglh di- rection and the internal injured situation would be discussed qualitatively.
