The dynamic moduli of Elasticity of Sand are indispensable to the calculation of the Seismic Earth Pressure on the Quay Wall.
Thereat, the auther has measured them by the resonance method changing the Confining Pressure of Sands.
As a result, the dynamic moduli of Elasticity of Sands increase in simple proportion to the Confining Pressure.
Also, the Elastic wave velocity of ground where the sand has been taken, corresponds with the Velocity, calculated by the above Moduli.
In conclusion, the Elastic Constants of the back filling increase in proportion to the depth.
