Abstract:

Base on large number of researches before, and according to traditional SMR（slope mass rating）, whose shortage is not consider slope weak rock mass interbed influences the slope rock mass evaluating result, the adjusting weight item of intensity difference is introduced. Through investigating 80 redbed soft rock slopes in Southwest China area, it is shown that the SMR modified by the difference of rock character is betten than the traditional SMR in practical situations; so that the modified SMR is more reasonable using in redbed soft rock slopes appraisement.

Key words: redbed soft, slope, rockmass classification, slope mass rating
