本文在收集了大量的边坡工程知识、经验、信息，特别是参考了英国煤炭露天开采委员会（BritishCoalandOpencastExecutive）近10年来对240个不稳定边坡的调查研究结果的基础上，以专家系统框架Xi－Plus为蓝本，建立了边坡稳定性分析专家系统。最后，又用一个现场实例对该系统进行了验证。结果表明：该系统能够较为精确地确定边坡的稳定状态、影响边坡稳定性的主要因素和可能的滑坡模式。 Based on a large amount of slope engineering knowledge, experience and information, especially referring to the survey results of 240 unstable slopes in recent 10 years by the British Coal Opencast Executive, this paper takes the expert system framework Xi -Plus blueprint, established a slope stability analysis expert system. Finally, the system is validated by a field example. The results show that the system can determine the stability of the slope more accurately, the main factors that affect the stability of the slope and the possible landslide modes.
