理论接触面
理论接触面-
基于增量弹塑性理论，引入接触面单元来模拟格栅纵横肋与土的相互作用，建立了土工格栅加筋土的动弹塑性本构模型、以及动力计算模型。
Basing on the elastoplastic incremental theory , and introducing the contact surface element to simulate the interaction between the longitudinal ribs , transverse bars and the soils ; accordingly , a dynamic elasto-plastic constitutive model of reinforced earth by geogrid is established for numerical calculating .

在该理论中分别对影响非线性相互作用的两个重要问题，即土体动力本构理论和接触面理论，进行了深入探讨。
Two theories included in it , soil dynamic constitutive theory and contact theory , are discussed .
