MARGIN: 0cm 0cm 0pt" class=MsoNormal>In order to overcome the defects in the existing modified mass rating system originated from slope rock mass rating (SMR) system, a more rational correction model was adopted to establish a modified Chinese hydropower slope rock mass rating (M-CSMR) system based on thirty six hydropower slopes. The coefficients of slope types were used to take the place of excavation factor to comprehensively take into account the influences of excavation, water erosion and scour on rock mass stability; the influence of slope height on rock mass stability was introduced into this system, and its grading and rating principle were given; the weights of factors in the SMR system were re-adjusted. Compared with other systems, the M-CSMR system’s evaluation results are closer to the empirical rating based on safety of factor, thus M-CSMR is a better hydropower slope rock mass rating system.ml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
