흙과 보강재의 마찰거동에 관한 연구 = A study on the Friction Behavior between Soil and Reinforcement

다국어 초록 (Multilingual Abstract)

Model tests have shown a quite specific type of friction to occur in reinforced earth structures between soil and reinforcement.
The coefficient of friction, is not a constant, rather it becomes smaller as overburden pressure increase and it can be considerably greater than the internal coefficient of friction of soil.
The aim of this study was to find a physical explanation for this phenomenon.
The friction obtaining soil and reinforcement was investigated in the laboratory using shear tests
Failure at a soil and reinforcement interface is not ideally plastic and for that reason the stress state, and the strain state must be considered.
A energy equation was applied to the results of the shear tests and the shearing resistance was found to be composed of two components, plastic state friction and soil dilatancy.
