摘　　要：针对土的双曲线模型和D P模型进行了研究 ,并用数值模拟方法对算例进行了分析。指出土力学与土工技术中的计算问题要得到切实合理的解决 ,就应该将土作为土体 ,掌握土的应力、应变和时间的本构关系。According to the hyperbolic model and D P model of soils in this paper the numerical simulation is used to analyze calculation examples. Author points out that in order to acquire reasonable and practical solutions for the computational problems of soil mechanics the soil should be regard as soil body and the constitutive relation among stress, strain and time should be grasped.
