摘要：

A large amount of analyses of model test and in-situ test results show that both light dynamic penetration and cone penetration tests can be used in testing the relative density of the back filling by coarse sand in highway roadbed construction; and there are good linear relationship between blow count N-10 and static point resistance Q(c). In order to disclose the root of the pertinence theoretically, Lade model is applied to three-dimensional finite analysis to simulate the two test processes; it is proved that the stresses, strains and displacements around the two kinds of test cones have great comparability.
