To rapidly and accurately assess the stability of Fujian highway slopes whose tops are composed of soil and loots are of rock, and the partial sliding phenomenon after excavation or after and before support, based on limit equilibrium method, this paper presents a soil and rock mass quality estimation method. For the first time, the soil and rock mass quality estimation were put together to evaluate the slope stability, which expanded the scope of rock mass classification system. One hundred and two slopes along sevenhighways in Fu-jian province were used to verify the suitability and accuracy of this method. The soil and rock mass quality es- timation method enriches the theoretical system of slope stability, and provides a new approach to the stability assessment of soil and rock slopes.%福建省高速公路边坡上部为土下部为岩，整体稳定状态良好，为对在开挖后及支护前后出现局部滑塌现象的岩土边坡进行快速、准确的稳定性评价，基于极限平衡法，提出一种适合于岩土边坡岩土体质量评价的方法，首次综合岩和土的质量评价方法对边坡稳定性进行分析，扩充了边坡岩体分级的范畴．用该法评价福建省7条高速公路的102个边坡，结果与实际情况非常吻合，证明了该方法的合理性和准确性．岩土体边坡的质量评价方法丰富了边坡稳定性评价理论体系，为岩土边坡的稳定性评价提供了一种新的途径．
