分析了Drucker-Prager(D-P)系列准则的应用条件及相互间关系,导出了各准则间的转换公式,结合算例基于强度折减法,采用位移突变判据和塑性区贯通判据,分别计算分析了M-C和D-P准则下的安全系数,并探讨了各准则的选取对计算结果的影响。
The application conditions and mutual relations of Drucker-Prager (DP) series are analyzed, and the formulas for the transformation of each criterion are derived. Based on the strength reduction method and the criterion of displacement mutation and plastic zone penetration criterion, the calculation formulas The safety factors under the MC and DP criteria are discussed, and the influence of the selection of each criterion on the calculation results is also discussed.
