摘要
首先介绍了非连续变形分析法的基本原理，然后以一条形浅基础为例，基于普朗德尔－瑞斯纳理论划分块体单元，用非连续变形分析法计算了在不同条件下地基的极限承载力。与索科洛夫斯基理论解对比表明，用非连续变形分析法计算地基的极限承载力是可行的。
The fundamental formulation of DDA is introduced first in this paper, and then a strip foundation discretized based on the Prandtl-Reissner's theory is taken as examples to com- pute its bearing capacity under different conditions . lt is shown that the simulated bearing ca- pacity using DDA is found to be in good agreement with that obtained from the general solu- tions presented by Coko The results have demonstrated that DDA is applicable to theanalysis of bearing capacity of shallow foundation.
