偏因子设计在岩土工程中的应用已经争论了几十年。尽管这种方法有一些明显的、被普遍接受的好处，但事实证明，在计算过程中应该在哪里应用部分因子很难达成一致。在这篇文章中，认为四个问题应决定在计算中应用系数的点：·系数应直接涵盖计算中涉及的主要不确定性，同时还应充分涵盖次要不确定性·系数应导致几何形状和强度都足够且相容的设计·系数不应应用于可能因平衡载荷(作用)而变得可忽略的量
The application of partial factor design in geotechnics has been under debate for several decades. Although the approach has some obvious, and generally accepted, benefits, it has proved very difficult to reach agreement on where in the calculation process partial factors should be applied. In this paper, it is argued that four issues should determine the point in calculations at which factors are applied: • the factors should directly cover the principal uncertainties involved in the calculation, whilst also adequately covering secondary uncertainties • the factors should lead to designs in which both geometry and strength are adequate and compatible • the factors should not be applied to quantities which may become negligible as a result of a balance between loads (actions)
