| 摘 要： | 围岩稳定性评价涉及许多不确定因素。由于集对理论和联系熵模型能有效地处理不确定问题，故将联系熵方法应用于围岩分类，建立矿岩分类的联系熵模型，计算围岩的联系熵值，相应地进行矿岩稳定性等级评价。是对系统不确定性进行量化的一种尝试，为矿岩稳定性评价提供了一种新的方法。实例模型表明，联系熵越大，则矿岩的稳定性越差，越危险。

| Abstract: | A great deal of factors evaluating the adjoining rock stability is uncertain. As the set pair system and connection entropy model can dispose the uncertain problem, a connection entropy model for stability evaluation of adjoining rock is presented. By calculating the connection entropy values at different safety gradation,the stability grade of adjoining rock could be obtained. The method could provide a new way to evaluate uncertain system like stability evaluation. The case study shows that the bigger the connection entropy value is, the worse the rock stability is, i.e. the more dangerous adjoining rock is. |
