- 简介：
- Rankine’s and Coulomb’s theories on earth pressure are classical methods being taught at universities, and are used daily in retaining wall design. However, according to the review article “Landmarks on Early Soil Mechanics” by the late Professor Skempton (1979), Boussinesq’s (1885) formula on earth pressure coefficient actually outperformed both Rankine’s and Coulomb’s theories when they are compared to the well-accepted numerical results by Caquot and Kerisel (1948). Surprisingly, even with Skempton’s favorable comment on Boussinesq (1885) theory, it remains relatively unknown. It is a lost treasure in the academic world and practicing world. No proof on Boussinesq’s elegant formula can be found in the English literature (including Skempton’s paper). In this presentation, we will present a complete proof of this lost treasure.

报告介绍：
This report discusses the underappreciated theory of Boussinesq's earth pressure coefficient which outperforms both Rankine’s and Coulomb’s theories when compared to accepted numerical results. A complete proof of Boussinesq’s elegant formula will be presented. This new solution satisfies equilibrium equations, yield conditions, free ground surface conditions, and frictional contact conditions on retaining walls. The lecture aims to popularize this forgotten formula for academics and practicing engineers.
