摘　　要：以206国道某段改扩建工程建设项目填石路基施工为研究对象,研究填石路基压实工艺、质量检测方法。通过试验段提出两种路基压实工艺,并进行数值模拟与试验段对比分析,找出适合本工程的最佳路基压实工艺,同时通过孔隙率检测、沉降差与累计沉降、工后沉降进行效果验证,结果表明,该压实工艺效果好,具有推广价值。Taking the construction of rockfill roadbed in the reconstruction and expansion project of a section of National Road 206as the research object,the compaction technology and quality detection method of rockfill roadbed are studied.Two subgrade compaction processes are proposed through the test section,and the numerical simulation and comparative analysis of the test section are carried out to find the best subgrade compaction process suitable for this project.Meanwhile,the effect is verified through porosity detection,settlement difference,cumulative settlement and post-construction settlement.The results show that the compaction process has good effect and has the value of popularization.
