The Determination of the Equivalent Vertical Spring Constant of Layered Subsoil

Zhou Guanglong  
This paper presents a method of determining the equivalent vertical spring constant of layered subsoil. The derivation is based on an elasticity formula in succinct form, so that both accuracy and simplicity are secured. An accessary chart is provided for further labour saving.ln principle, this method may also be used to deal with the equ(?)valent Winkler's modulus or Young's modulus of layered media for the calculation of beams on elastic foundations.
