摘　　要：文章阐述了目前旧路路基存在的病害,分析了旧路路基检测方法与检测参数,结合工程实例,提出采用落锤式弯沉仪和承载板,对旧路路基承载力进行检测。研究结果表明,两种方法的检测结果具有一致性,相关系数达到0.95以上,为改扩建工程决策制定提供了科学依据。This paper expounds the existing diseases in the old road subgrade,analyzes the detection methods and detection parameters of the old road subgrade,and puts forward the use of Falling Weight Defl ectometer and bearing plate to detect the bearing capacity of the old road subgrade in combination with engineering examples.The results show that the detection results of the two methods are consistent,and the correlation coeffi cient reaches more than 0.95,which provides a scientifi c basis for the decision-making of the reconstruction and expansion engineering.
