摘　　要：冲击压实是解决路基深层压实问题的新技术,但深层压实质量的评定却难以使用传统的检测方法。通过MATLAB最小二乘回归分析法建立累计沉降量与路基压实度的经验关系式,把对路基压实度的质量控制转化为对累计沉降量的控制,实现路基深层压实质量的快速评定。研究表明使用经验关系式得到的压实度预测值与实测值最大相对误差为1.97%,满足检测要求。Impact compaction is a new technique to solve deep compaction problem for road bases but traditional checking method is difficult to assess the deep compaction quality.An experiential formula between accumulated sedimentation and the base compactness is set up with the least square regression analysis in MATLAB so the quality control of base compactness is converted to the accumulated sedimentation control and rapid assessment for deep base compaction quality is realized.Research shows that the prediction compactness value obtained from the experiential formula is in 1.97% relative error compared with the real test value,which meets the requirements of checking.
