摘要
根据断续节理岩体模型试验得到的岩桥贯通机理，建立起表征岩桥初裂强度和不同破坏模式下的贯通强度计算公式。计算结果表明，所建立的强度计算模型和模型试验结果基本吻合。因此，本研究成果对正确认识断续节理岩体的强度特性，具有较高的理论和工程应用价值。
The formulae for initial fracture and coalescence strength of discontinuous jointed rockmass under different coalescence modes are set up according to the coalescence mechanism obtained from simulation experiments. The results obtained from the formulae are basically in consistent with those obtained from experiments. The conclusions are of both theoretical and practical significance to realize the strength features of discontinuous jointed rockmass.
