Prandtl和Terzaghi地基承载力公式是土力学中的经典公式,也是塑性力学的基本课題之一。本文针对适用于土的Coulomb-Mohr屈服准则,采用塑性力学的滑移线解法,系统的推导了Prandtl和Terzaghi公式。
The formula of bearing capacity of Prandtl and Terzaghi is a classical formula in soil mechanics, and it is also one of the basic topics of plastic mechanics. In this paper, the Coulomb-Mohr yield criterion applicable to soils is adopted. The slipline solution method of plastic mechanics is used. The Prandtl and Terzaghi formulas are derived systematically.
