摘要
岩石的抗拉强度是岩石的一个重要力学性质,也是岩石结构设计安全与稳定性分析的一个控制参数。由于岩石材料的特殊性,岩石抗拉强度的测定结果往往会出现较大的离散性,其中岩石抗拉强度计算式的简化也是产生误差的一个重要原因。通过几个有代表性抗拉强度计算式的理论分析与对比研究,从理论上证明这一误差产生的原因和解决的途径,为精确测定岩石抗拉强度提供了理论依据。
Tensile strength is one of the most important mechanical properties of rock and also a controlling parameter of rock for design、safty and stability analysis of rock structure. Testing results of tensile strength will be generally different largely for different rock due to their particularity. Also, the simplification of the formula for calculating tensile strength can cause error. Finally, the error cause and resolution is proved theoretically through the theoretical analysis and comparison research for several typical tensile strength formula, which provides theoretical grounds for refined calculation of rock tensile strength.
