| 摘 要： | 为解决各种概念分歧，采用神经网络方法建立了非饱和土的广义吸力模型．该模型理论突出了土的微结构效应，将微结构状态和含水量状态结合起来研究非饱和土的吸力和有效应力，认为广义吸力由土体微结构和含水状态惟一确定。

| Abstract: | To resolve the disputes of some basic concepts, the generalized effective stress principle of unsaturated soils was established by the neural network technology, and the soil microstructure is emphasized in the model. The suction and effective stress of unsaturated soils are analyzed by combination concepts of the microstructure with water content, and the generalized suction is only determined by the two concepts. |

| Keywords: | soil micromechanics unsaturated soil suction effective stress |
