摘要
应变梯度的研究近年来在理论和实验上都取得了长足的发展。综述应变梯度理论在岩土力学中应用的研究现状,系统说明各种考虑应变梯度的模型的理论来源和及其相互联系,并对各种模型作了简要述评,就应变梯度理论在岩土力学中的发展趋势提出初步看法。
Researchs on strain-gradient have made great developments in theories and experiments in recent years. The applications of strain-gradient theory in geotechnical mechanics have been reviewed in this (paper). The origin and interrelation of different strain-gradient models were illuminated and evaluated (numerically). The prediction on the development trend of strain-gradient theory in geotechnical mechanics were proposed.
