摘要
极限分析和安定分析的近代发展方向是寻找通用性强、计算效率高的数值方法。本文介绍将有限单元法和数学规划法相结合的、同时适用于极限分析和安定分析的统一数值方法，包括下限格式和上限格式。
The modern trend of limit analysis and shakedown analysis is to find some numerical methods,which are general purpoful and more efficient.In this paper,two uniform numerical methods forlower bound solution and upper bound solution of limit analysis and shakedown analysis are intro-duced. The metheds are based on an algorithm to combine the finite element method with the mathe-matical programming.
