中文摘要	针对以往本构模型或过于简单而不能全面描述土体的性质,或过于复杂而不便于应用的问题,以非线性弹性、弹塑性、艳正曼辛准则及Singh-Mitchell蠕变模型为基础,并将曼辛准则扩展至三维,建立了一种简单实用而又能同时合理地考虑土体非线性、动力滞回和流变特性的统一弹塑-黏塑性本构模型.通过试验模拟,验证了该模型的合理有效性.; Most existing constitutive models either cannot fully describe the mechanical properties of soils due to their simplicity,or cannot be applied easily due to their complexity and the difficulty of calibrating too many parameters.Based on the theories of nonlinear elasticity,elastoplasticity,modified Masing rules and the Singh-Mitchell creep model as well as the generalized Masing rules for 3D application,a simple,practical and unified elastoplastic-viscoplastic model considering the nonlinearity,cyclic hysteresis and creep behavior of soils is proposed.It has been validated through the tests.The present model is simple and convenient because the parameters have clear physical meanings and are easy to calibrate.; 国家自然科学基金(50408002)
