一、公式的推导关于地基极限荷载的计算及地基的稳定性问题,在苏联学者的著作中已发表过很多论述。本文只是在叶夫道基莫夫工作的基础上作了进一步的分析与推导,得出以基础宽度b、侧超荷载q、土的容重Υ、土的内摩擦角ψ及内聚力c来直接表示的极限荷载公式。在平面问题中,地基达到塑性平衡时出现滑动线网。根据摩尔的破坏理论,在滑动线网范围内的任意点都满足塑性平衡条件方程 First, the derivation of the formula With regard to the calculation of the ultimate load of the foundation and the stability of the foundation, many statements have been published in the works of Soviet scholars. This paper is based on Yevkov’s work and further analysis and derivation. It is based on the basic width b, side over load q, soil bulk density Υ, soil internal friction angle ψ and cohesion c to directly represent The ultimate load formula. In the plane problem, sliding nets occur when the foundation reaches plastic equilibrium. According to Moore’s damage theory, the plastic equilibrium condition equation is satisfied at any point within the sliding wire mesh
