摘　　要：利用FWD进行水泥稳定土路基模量的检测与评价,依托两段高速公路路基工程,进行水泥稳定土路基现场FWD检测及室内动三轴试验。经研究发现,利用FWD进行路基模量计算的结果与动三轴试验结果相关性良好,同时利用双层弹性体系进行路基模量计算结果与三轴试验更加接近。这为合理利用FWD进行水泥稳定土路基现场检测提供参考。FWD is used to detect & evaluate the modulus of cement stabilized soil subgrade, and on-site FWD detection & indoor dynamic triaxial test of cement stabilized soil subgrade are carried out based on the subgrade works of two sections of expressway. It is found that the results of subgrade modulus calculation using FWD have good correlation with the results of dynamic triaxial test, and the results of subgrade modulus calculation using double-layer elastic system are closer to those of triaxial test, which may provide a reference for the reasonable use of FWD in the field detection of cement stabilized soil subgrade.
