摘要
把筋材的作用等效成附加应力（等效附加应力）作用在上骨架上，从而可以把加筋土当成素土来计算。这种新的计算方法思路明晰，参数推求简单，并可利用现有的土的本构模型，不需要针对加筋土引进新的模型。笔者在以往工作的基础上，通过试验，把附加应力的计算与加筋方向上的应变直接建立关系，给出了求取参数的办法，从而使进一步的有限元计算比较容易实现。
The analysis of reinforced soil may be conducted as pure soil according to a new Method,in which the effect of reinforcing materials is considered as an equivalent additional Stress and included into the soil skeleton.Analysis of texsol casn be conducted on the basis of Current constituive models without ineroducing new models.The direct relationship between Equivalent stress and the strain in reforfcing direction,together with the calculating method of Parameters are described in the paper.
