| 摘 要： | 坡高与边坡稳定性有密切关系。CSMR分级体系在SMR的基础之上针对水电边坡工程引入了坡高修正系数 ,但在公路边坡分级实践中发现 ,该坡高修正系数仍有待于改进。对各类边坡可能失稳形式的力学分析 ,证明坡高修正系数 ξ可近似表示为ξ =a+b/H 的形式。通过对 1 0 0余个边坡样本统计分析 ,得出两种不同岩层、坡面产状组合形式下坡高修正系数的数学表达式。经检验 ,改进后的CSMR体系能够满足公路边坡稳定性初步评价的要求。

| Abstract: | Slope height is a controlling factor in stability of a slope. Based on the SMR system, the slope height coefficient is incorporated in CSMR, a system developed for hydroelectric slope rock mass rating. To apply the rating system in the classification of highway slopes, further modifications should be made. The slope height coefficient ξ can be expressed as ξ=a+b/H based on the mechanical analyses of some possible failure forms. This paper then presents two expressions of slope height coefficient for different combinations of strata and slope from statistic analyses of over 100 slopes. The modified CSMR has been validated and meets requirements for assessment of highway slope stability. |
