Preliminary Study on Vertical Subsoil Participating Mass

Article Preview

Abstract:

A quantificational calculation method of participating mass of foundation vertical vibration is presented in this paper. Vertical subsoil participating mass of strip and rectangular foundation are preliminarily calculated based on Boussinesq’s solution of subsoil additional stress and equivalent-load method. That is, the subsoil participating mass can be calculated only prescribing the isoline of additional stress. The method is suitable for adopting by corresponding codes for it avoids considering complicated influencing factors of subsoil.
