【Abstract】 A new method for quick and non-destrustive examination of the compactness of coarse grained soil roadbed is presented. On the basis of theoretical analysis and examining verification, the distinct relationship between the compactness of coarse grained soil roadbed and speed of rayleigh wave is found. Making use of this kind of relation can quickly exame the compactness . According to experiments and research, the accuracy of examnation can satisfy the engineering requirements.更多还原
