摘　　要：根据岩石优势结构面确定的特点,提出了一种既可以考虑结构面数量优势又可以考虑结构面质量优势的确定岩体优势面的新方法:改进功效系数法.总结出了结构面评价的6组重要优势指标,并对改进功效系数法中的各个指标评价档次的选择进行了讨论.实例验证结果表明,新方法是合理有效的.Based on the characteristics of rock structural planes, a new method to determine the preferred structural plane of rock, the improved efficacy coefficient method, is presented. The method considers not only the quantity predominance but also the quality predominance. Six groups of preferred indexes for evaluating the structural plane are summarized, and the process of classifying the indexes of the improved efficacy coefficient method is discussed. An application example shows that the method is reasonable and effective.
