摘　　要：首先介绍了未确知信息理论的概念及其应用领域,指出了传统均值法处理数据存在的问题,对未确知信息数学处理方法和过程进行了简要说明。运用这一处理方法对黄河上游某电站坝址岩体变形模量的取值进行了论证,并对两种方法得到的结果进行了对比。结果表明这一方法在不确定性信息处理中比传统方法具有更多的优点,能够给出不同保证率下的岩体变形模量值,表明其处理数据更精细、更科学,值得在地质工程相关数据处理中进一步探讨和应用。The conception and application field of the unascertained information is firstly introduced, the problem produced by conventional averaging method is pointed out, and the processing method and the course of the unascertained information is explained briefly. Using this processing method, the paper argues the rock-mass modulus of deformation of a certain hydrostation located in the HuangHe upstream, and compares the two results by the averaging method and the method of the unascertained information. The result indicates that the latter has more merits than the former: it can provide the rock-mass modulus of deformation according the different reliability. These indicates that the method of unascertained information is more appropriate and worth further discussing and applying in the field of the data processing of the geology engineering.
