초록

본 논문에서는 표준 탄성-소성-점성 관계식에 근거하고, 수식을 간략화하기 위한 몇 가지 가정을 도입하여 전단속도에 능동적으로 대처할 수 있는 비교적 간단한 구성모델을 개발하였다. 개발된 모델은 정규압밀점토의 음력경로를 비교적 성공적으로 묘사하였다. 개발된 모델에서는 하나의 전단속도에서 결정한 모델변수 값들을 다른 전단속도 경우에도 적용할 수 있다는 장점이 있다. 모델변수 및 모델의 추가 간략화는 연속된 논문에서 설명된다.

A rate-sensitive constitutive model was developed, with some simplifying assumptions, in the frame of the standard elastoplastic-viscous relation. The simulations performed using the model were successful for the normally consolidated cohesive soils with the advantage that the parameter values determined at a rate could be used at. different rates. Details on the parameters and additional modification of the model are presented in the successive paper.
