| 摘 要： | 在内变量不可逆的热力学理论框架下,从能量的角度出发,讨论了水压致裂测试中岩石变形破坏中的能量耗散、能量释放与岩石强度和破坏的内在联系.同时基于能量耗散与释放原理推导出水压致裂法测量地应力岩体破坏时的临界应力公式,并应用上述公式结合水压致裂第一循环对某抽水蓄能电站地应力测量中的最大水平主应力进行计算,其计算值与传统理论计算值比较接近,表明所给出的临界应力公式是合理的.

| Abstract: | Within the irreversible thermodynamics framework and on the viewpoint of energy, relationships of energy dissipation, energy release, intensity and failure of rock are discussed when the hydro - fracturing method is carried for in - situ stress test. Meanwhile, based on the principle of energy dissipation and release, the critical stress state of rockburst is proposed. The equation of critical stress state has been applied to calculate the maximal horizontal principal stress combining with the first cycle curve of hydro - fracturing measurement in a pumped storage plant. Calculated results by the equation matches the results by traditional theory, which proposed the equation is reasonable. |
