摘　　要：为分析逆断层附近的埋藏方位对岩石力学性质的影响,通过井下水平定位装置和岩芯钻机,将逆断层附近预定水平方向岩石从取芯点取出,标记的3D坐标状态,然后使用室内二次固定角和凿岩机取出空间6个方向的岩样。从岩石的峰值强度、破坏形态两个角度来综合分析岩体空间力学性质,利用RMT-150B岩石力学试验系统结合声发射仪,对不同方向岩样进行单轴压缩试验,将试验结果以图形和表格的形式进行分析。In order to analyze the influence of the buried orientation near the reverse fault on the mechanical properties of the rock, through the horizontal positioning device and the core drilling rig, the rock in the pre- determined horizontal direction near the reverse fault in the drilling hole is taken out from the coring point and marked in the 3-d coordinate state. Then the rock samples in 6 directions in the space are taken out by the second fixed angle in the chamber and the rock drill. The analysis is based on the peak strength and the failure mode of the rock. Using RMT-150 B rock mechanics test system combined with acoustic emission device, u- niaxial compression tests were carried out on rock samples of different directions, and the experimental results were analyzed in the form of graphs and tables.
