堆石料Wang-Wu亚塑性本构模型参数求取的改进
Improved method to parameters of the rockfill Wang-Wu hypoplastic model
摘要
Abstract
The Wang-Wu hypoplastic model was studied and its defect of the model used in rockfill materials was pointed out. According to the derivation of the model parameters equation, the relation-ship between the parameters and the confining pressure was established and the new model parameters were proposed. The method was verified by means of rockfill oedometric test, rockfill triaxial consoli-dated drained test, Duncan E-B model inversion test and modified Shen Zhujiang' s double-yield sur-face model inversion test. It was shown that the proposed seven new parameters could effectively solve the problem of determining the parameters when the model was introduced into the rockfill materials, and it is helpful for the model to be extended to the rockfill material engineerings.关键词
