%X 分析低路堤路基健康状况影响因素，考虑到低路堤易受交通荷载和干湿循环荷载的影响，建立以地基层、路基层为内部影响因素、水系统、交通荷载为外部影响因素等综合4个方面12个因素为评价指标的低路堤路基健康状况评价体系，并使用二次物元模型进行评价。在浙北低路堤段工程实例应用，评价结果表明，此低路堤路基健康状况为中度，评价结果基本与现场调查结果一致，证明所建立的低路堤健康状况评价模型的可行性。本文方法将定性与定量有机地结合起来，使得评价结果更为合理和可靠，为高速公路低路堤路基健康状况提供了一条新的思路和手段。<br>This paper analyzed the factors which affect the health status of low embankment. In view of the low embankment is affected by the traffic load and dry-wet cycle load, a performance evaluation system considering 12 factors was established, including the base and subgrade layer for internal traffic load factors, and water system. To test the presented model, a low embankment engineering case was introduced. Evaluation results show that the low embankment condition is moderate. The evaluation results agree well with the field investigation results, which demonstrates the feasibility of the proposed model in low embankment health evaluation. This method combines the qualitative and quantitative organically, making the evaluation results more reasonable and reliable. It provides a new solution for the low road embankment health condition
