摘　　要：研究公路路基工程中试验检测方法,以湖北省十堰市郧阳区柳陂镇至五峰乡二级公路路基工程为例,分别采用灌砂法与回弹弯沉检测方法检测公路路基压实度与路基弯沉试验检测。试验结果表明:通过灌砂法检测公路路基试验,得出公路路基压实度试验检测结果,即6个检测桩号的路基实测压实度均>95%,均符合公路工程路基压实度质量检测标准。采用回弹弯沉检测得出路基的弯沉代表值为23.7(0.01 mm),且路基弯沉的合格率高达98.41%,通过合理选择和应用试验检测方法,能够有效提升路基工程的检测效率。The test and detection methods in highway subgrade engineering are studied.Taking the subgrade engineering of second-class highway from Liupo Town to Wufeng Township,Yunyang District,Shiyan City,Hubei Province as an example,the sand filling method and rebound deflection detection method are respectively used to detect the compactness of highway subgrade and subgrade deflection test detection.The test results show that by using the sand filling method to test the road subgrade,the compaction degree test results of the road subgrade were obtained,that is,the measured compaction degree of the 6 test pile numbers of the road subgrade was all greater than 95%,which meets the quality inspection standards for road subgrade compaction degree in highway engineering.The representative value of roadbed deflection obtained through rebound deflection detection is 23.7(0.01 mm),and the qualified rate of roadbed deflection is as high as 98.41%.By selecting and applying appropriate testing methods,the detection efficiency of roadbed engineering can be effectively improved.
