摘要
根据随机模糊概率理论，讨论了岩体力学参数随机模糊概率分布形式，提出“置信阈值”的概念和置信度分析模型。以此为基础，从理论上分析了力学参数取值的置信度问题；并就参数的可靠性分析提出了测试参数的可靠性检验方法。研究表明，文中所提的方法不但合理，而且符合工程实践。
The probability distrbution of mechanical parameters is discussed, and the concept of believable threshold and the model of believable degree are put forward. Furthermore, based on this concept, the question of the believable degree of mechanical parameters is analysed theoretically, and the method of reliability test is suggested.
