本文主要是阐述散粒体极限平衡理论在计算挡水、挡土建筑物地基极限荷重中的应用.文中,首先说明了这一问题的提法及其边界条件和解题的一般原则;然后推导了不考虑土体自重的水平极限荷重的普温公式,并附有考虑土体自重时的计算实例;最后讨论了应用极大极小原理的近似解法,提出了一种可静解和一种可动解的计算公式,并举例说明了这种解法的可靠性.可静解法的计算比较简便,虽误差较大,但偏于安全,可以在实际中应用.
This paper mainly expounds the application of the limit equilibrium theory of bulk-granules in calculating the limit load of retaining and retaining foundations. In the article, the formulation of the problem and its boundary conditions and general principles of problem solving are first illustrated; The Putin formula that does not take into account the horizontal extreme load of the soil mass, together with examples of calculations taking into account the weight of the soil, discusses the approximate solution using the minimax principle, and proposes a solution and a solution. The calculation formula of the movable solution and the reliability of the solution are illustrated by examples. The calculation of the static solution method is relatively simple. Although the error is large, it is safer and can be applied in practice.
