为了能够高效全面地评价公路路基排水状况,提高评价的准确性,通过对路基排水状况影响因素的分析,建立了一套公路路基排水状况评价指标体系;研究提出了基于熵权的公路路基排水状况评价方法,并通过实例对公路路基排水状况的评价结果做出了分析。实际应用表明,该评价指标体系与评价方法使得评价结果更加客观合理,为路基的设计施工以及日常的养护管理提供了参考。 In order to evaluate the drainage status of highway subgrade efficiently and comprehensively and improve the accuracy of evaluation, a set of evaluation index system of highway subgrade drainage condition was established by analyzing the influencing factors of subgrade drainage status. The paper also proposed the drainage condition of highway subgrade based on entropy weight Evaluation methods, and through examples of the evaluation of highway subgrade drainage conditions made the analysis. The practical application shows that the evaluation index system and evaluation method make the evaluation results more objective and reasonable, which provides a reference for the design and construction of subgrade and routine maintenance and management.
