摘　　要：为了保证垃圾填埋场的安全可靠,垃圾填埋场的沉降规律一直是填埋场研究中的重要课题。采用层次法和关联度法对填埋场稳定化影响因素进行分析,结果表明:渗滤液流量是影响垃圾填埋场稳定化最显著因素之一;以沉降量值为分析因子的灰色理论对垃圾填埋场稳定化问题进行了研究,结果表明:沉降实测值在经历了增长过程之后逐渐趋于稳定,当时间积累足够长,预测值远远超过实测值,说明此方法适合于短期评价。Settlement is an important index and macroscopic performance indicator of stabilization process in landfill. Therefore, in order to ensure the safety of landfill, the settlement of landfill has been an important issue for various studies. In this paper the influence factors of landfill stabilization were analyzed using hierarchical method and relative degree method. The results show that the leachate flow is one of the most significant factors affecting the landfill stability. Using settlement value as a parameter, the landfill stabilization was evaluated based on grey system theory. The results show that the measured settlement value gradually becomes stable after a long growth process. When the time is longer enough, the predicted value exceeds the measured value. Thus this method is suitable for short-term evaluation.
