本文阐明了套筒致裂岩体应力量测的基本原理、套筒致裂技术.介绍了用石腊-砂子模型模拟岩体的套筒致裂试验结果和试验结果的分析,证明了套筒致裂岩体应力量测理论的正确性,揭示了裂缝的扩展规律,明确了利用压力-体积变化曲线的拐点确定关闭压力值,从而求出最小主应力和最大主应力,是合理的. In this paper, the basic principles of stress measurement of sleeve-cracked rock mass and the sleeve crushing technology are described. The sleeve cracking test results using the paraffin-sand model to simulate the rock mass are introduced, and the analysis of the test results proves that the sleeve The correctness of stress measurement theory of cracked rock mass reveals the law of crack propagation, and it is clear that using the inflection point of the pressure-volume change curve to determine the closing pressure value and thus find the minimum principal stress and the maximum principal stress are reasonable.
