中文摘要：

基于 Mohr 库仑(M-C ) 标准，为 geomaterial 的 Druker-Prager (D-P ) 标准的参数在非联系的流动统治下面被决定，并且因此，一个新 D-P 类型标准被介绍。二个假设在推导期间被采用：1 ) 由 M-C 模型和 D-P 模型的主要种类是相等的，并且 2 ) 材料在飞机种类状况下面。在飞机上基于表面的分析，比有 M-C 的 D-P 标准约束圆或 M-C 刻写圆的，建议 D-P 类型标准才好，并且为压力矿脉角度是适用的不到零。由在飞机种类状况和另外的 D-P 标准下面把预言的结果与沙的测试数据作比较，建议标准被验证并且与测试数据同意很好，它进一步在矿脉角度的某些范围比另外的 D-P 类型标准更好被证明是。标准被用户子程序编进有限差别包裹 FLAC3D，并且被用来由力量减小方法分析一个斜坡的稳定性。从建议标准的预言的斜坡安全因素由斯宾塞方法与那同意很好，并且它从经典 D-P 标准是比那更精确的。

英文摘要：

Based on Mohr-Coulomb （M-C） criterion, the parameters of Druker-Prager （D-P） criterion for geomaterial were determined under non-associated flow rule, and thus a new D-P type criterion was presented. Two assumptions were employed during the derivation： 1） principal strains by M-C model and D-P model are equal, and 2） the material is under plane strain condition. Based on the analysis of the surface on rt plane, it is found that the proposed D-P type criterion is better than the D-P criterion with M-C circumscribed circle or M-C inscribed circle, and is applicable for stress Lode angle less than zero. By comparing the predicted results with the test data of sand under plane strain condition and other D-P criteria, the proposed criterion is verified and agrees well with the test data, which is further proved to be better than other D--P type criteria in certain range of Lode angle. The criterion was compiled into a finite difference package FLAC3D by user-subroutine, and was used to analyze the stability of a slope by strength reduction method. The predicted slope safety factor from the proposed criterion agrees well with that by Spencer method, and it is more accurate than that from classic D-P criteria.
