用BP网络识别岩土材料本构关系的研究

Study on Identifying the Constitutive Relation of Geo-materials by BP Network

探讨了应用BP网络识别岩土材料本构关系的可行性。用BP网络的最大误差学习算法对岩土材料本构关系进行了自适应辨别。研究表明 ,BP网络能充分体现岩土材料的非线性关系 ,具有较高的求解能力。

The feasibility of applying BP network to identify the constitutive relation of geo materials was studied.The maxium error learning algorithm of BP network was used in the self adaptive identification of the constitutive relation of geo materials.The study has shown that BP network can fully describe the non linear relationship of geo materials and has higher ability of solution.
