| 摘 要： | 本文运用断裂力学理论推导了含节理岩体的初裂强度公式,定量地讨论了节理方向、长度对岩石强度的影响,阐明了节理岩体强度各向异性的实质。通过证实,本文所建立的公式具有很强的适用性和较高的可靠性,可用于实际的工程岩体稳定性评价。

| Abstract: | In this paper, the formula of initial fracturing stength of rockmass containing intermittent joints is presented based on the theory of fracture mechanics. The effect on strength of orientation and length of joints is discussed quantitatively. At the same time, the essence of strength anisotropy is clarified The formula established in this paper can be effectively and reliably used in evatuating stability of rockmass |
