摘　　要：根据可拓工程理论,以布伦口~公格尔水电站地下洞室4个典型标段为例,建立改进的围岩评价物元模型。考虑实际工程中主客观因素对围岩质量评价指标权重的影响,将主成分分析赋权法应用到理论当中。研究结果表明,与其他围岩评价方法结果相比,改进后的可拓理论的围岩质量评价结果能够满足实际工程需要,并且能够为围岩质量进行科学评价提供理论依据。According to the extension theory,in-Bulunkou Gonggeer Hydropower Station underground caverns in 4 typical section as an example,a matter-element model of surrounding rock evaluation improvement. Considering the influence of the subjective and objective factors on the weight of surrounding rock quality evaluation index,the principal component analysis method is applied to the theory. The results show that： compared with the results of other evaluation methods of surrounding rock,rock quality evaluation theory that extension results can meet the needs of practical engineering can be improved,and can provide a theoretical basis for rock quality evaluation.
