土的应力-应变特性可分为硬化型和软化型，硬化型可经历三个阶段，软化型可经历两个阶段，非硬化型可经历三个阶段，软化型可经历三个阶段。对邓肯和张德昌提出的线弹性模型进行了修正，考虑了加载过程中土体的结构性损伤，并引入了损伤率的概念.对几种土的模拟结果与试验结果的比较表明，所提出的模型可以更准确地反映土壤的行为。
The stress-strain behavior of soil is classified into harden type and soften type.The harden type may experience three stages and soften type has two stages.The non-linear elastic model proposed by Duncan and Chang is modified with the consideration of soil structural damage during loading and the concept of damage rate is introduced.The comparison of simulation results with test data for several kinds of soil shows that the proposed model can more precisely reflect the behavior of soil.
