| 摘 要： | 对江西省境内5条高速公路土石混填路基进行了大量的动弹性模量和压实度试验,分析得到了动弹性模量和路基填料压实度的回归关系式,提出了基于路基动弹性模量的土石混填路基压实质量控制方法,给出了土石混填路基压实质量控制标准的建议值,通过现场检测对提出的建议值进行了验证.试验结果表明：土石混填路基的动弹性模量和压实度具有较好的相关性,动弹性模量可作为土石混填路基压实质量控制方法,动弹性模量作为路基压实质量控制建议标准是合理的、适用的.

| Abstract: | The dynamic elastic modulus test and compaction test was carried out on five expressways in Jiangxi Province,and regression equations between dynamic elastic modulus test and the degree of compaction was obtained.Quality control method based on dynamic elastic modulus was put forward.Suggested values of dynamic elastic modulus for controlling construction quality standards of earth-rock mixture were proposed and verified through field detections.The test results show that the dynamic elastic modulus and the... |
