摘要： 对广义CSMR法的前人研究成果进行讨论，提出考虑滑坡变形扰动效应的改进CSMR法，研究认为改进CSMR法更符合岩质滑坡的客观工程地质特征。采用改进CSMR法对典型岩质滑坡工程实例的稳定性进行研究，[JP2]通过与实例的勘察评价结果进行比较分析并采用了“CSMR值与稳定系数Ks”的经验关系式进行验证，认为改进CSMR法用于岩质滑坡的稳定性评价是适用的，提出了改进CSMR法评价岩质滑坡稳定性的一些具体认识和建议。

Abstract: This paper evaluates the recent developments in generalized Continuous Slope Mass Rating (CSMR) research. A modified CSMR method that considering the disturbance effects on the rock slides was proposed. This modified CSMR method has a better characterization of the geological conditions in rock slides. A typical rock slide site is evaluated with this modified CSMR method as a case history and the results are compared with the geotechnical investigation results. In the evaluation, relationships between the Stability Coefficient, Ks, and CSMR are applied. These results indicate that the modified method is appropriate in the rock slide evaluations.
