功效系数法在确定岩体优势结构面中的应用

首次将广泛应用于商业评估及预警的功效系数法应用于岩体优势结构面的确定中,提出了一种确定岩体优势结构面的新方法并对前人的方法进行了总结。克服了传统方法确定优势结构面只考虑数量优势而忽略了质量优势的缺点,使结构面评价趋于合理。总结出了评价结构面的六组重要优势指标,并对功效系数法中满意值和不允许值的选取进行了讨论,最后提出了应该注意的问题。

Application of efficacy coefficient method to determination of rock preferred structrual plane

The efficacy coefficient method was applied to determine the preferred structural plane of rock for the first time.The method had been used to evaluate and forecast the business affairs before.A new method was presented to determine the preferred structural plane of rock and the methods used before were summarized.The shortcomings of traditional methods were removed in this method,i.e.,only the quantity predominance was considered but the quality predominance was ignored,and then the rock structural plane could be evaluated more rationally.After six groups of predominant indexes were summarized to evaluate the structural plane and the satisfactory,and the unallowable indexes of improved efficacy coefficient method were discussed.
