摘　　要：根据瞬态瑞利波原理,研制路基压实质量快速监测仪器,探讨了仪器研制的关键技术,通过1 000多组对比试验,建立了地基系数K30和瑞利波波速RV的数学关系式。该仪器具有准确、快速、轻便的特点,可以替代K30、压实度等试验。Based on the principle of the transient Rayleigh wave technique, the rapid inspection instrument of subgrade compaction quality was developed. The key of technology is studied also. The mathematic formula between bedding value K30 and Rayleigh wave speed was built by more than 1000 groups field and laboratory simulataneous test. the testing results indicate that the rapid inspection instrument is of the specific character of accuracy, quick speed and lightweight. it can be used to replace bedding value K30 test and degree of compaction.
