水利水电工程地质勘察规范
Under the combined action of above - mentioned four factors , the complex rock mass at right bank which consist of two weak rock mass bands and superficial unloading relaxed rock mass came into being
其相关系数在0 . 85以上。在此定量化基础上，结合现场分类以及水利水电工程地质勘察规范，通过对比综合，得到研究区岩体质量分级。
After long - term synthetic action of these factors , the complicated rock mass in the right dam foundation come into being . the adjoining rock engineering geological classification of water - conservancy and hydraulic - power project reconnaissance code ( gb50287 - 99 ) , geomechanic system ( bieniawski , 1973 ) , rock mass quality index z ( xiaowang , 1995 ) , artificial neural network and field classification were used in the rock mass quality classification
本文采用水利水电工程地质勘察规范( gb50287 - 99 )的围岩工程地质分类、岩体rmr分类( bieniawski , 1973 ) 、岩体质量指数z分级(小湾, 1995 )以及人工神经网络分类，对坝区岩体按其基本指标作出定量化评分、分级。
