基于经验的优势断裂灰色分级

运用基于经验的灰色关联度分析法对控制大型工程区域稳定性的优势断裂进行分级，该方法以时间优势指标(RT)、规模优势指标(RL)、距离优势指标(RD)、活动周期与活动史指标(RR)以及综合指标(RZ)作为灰色关联度分析对象，并根据最大关联度识别原则，获得优势断裂等级的判定结果。这一方法克服了过去优势断裂评价中程序繁琐，各等级之间指标界限不明确的缺点，为优势断裂评价和优势面专家系统提供了新的思路。

Gray Classification of Preferred Faults Based on Experience

Based on experience, the preferred faults controlling the regional stability of large engineering can be classified by using the gray correlation degree analysis method. According to the recognition rule of the biggest correlation degree this method determines the grade of preferred faults by referring to the preferred indices which includes time index(RT), dimension index(RL), distance index(RD), activity period index and activity history index(RR) and comprehensive index(RZ). The old evaluation methods are more complicated and the boundaries between two preferred indices are not clear. The present analysis method overcomes the above mentioned shortcoming and can be used in the evaluation of preferred faults and expert system of preferred plane.
