چکیده مقاله
In the present paper the mechanical modeling of the dynamic load plate test with a new innovative device, namely Dynamic Load Cylinder DLC , is presented The DLC can be employed in construction sites in order to clarify the degree of compaction of the soil layers and to evaluate their bearing capacity estimating the dynamic modulus of soil The motion of the device is characterized by a mass spring system The mechanical models developed are intended to provide simple and efficient formulations, which allow a large number of numerical simulations at low expenses The results are statistically analyzed indicating that the R1 the first rebound of falling weight after the dynamic loading of soil in new device correlates relatively well with the Clegg value ASTM D 5874 – 95 for both the laboratory and field tests It is also shown that the btained dynamic modulus of elasticity from DLC is in good agreement with published results of the e E SEIS −MOD achieved from CBR test
